Composite resonances at a 10 TeV muon collider J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-17 Da Liu, Lian-Tao Wang, Ke-Pan Xie
We investigate the reach for resonances of the composite Higgs models at a 10 TeV μ+μ− collider with up to 10 ab−1 luminosity. The strong dynamics sector is modeled by the minimal coset SO(5)/SO(4), where vector resonances are in (3, 1) of SO(4) and fermions are in (2, 2). Various production and decay channels are studied. For the spin-1 resonances, the projections are made based on the radiative return

Effective dynamics of quantum fluctuations in field theory: with applications to cosmology J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-17 Ding Ding, Yu Zhao, Yidun Wan
We develop a novel framework for describing quantum fluctuations in field theory, with a focus on cosmological applications. Our method uniquely circumvents the use of operator/Hilbert-space formalism, instead relying on a systematic treatment of classical variables, quantum fluctuations, and an effective Hamiltonian. Our framework not only aligns with standard formalisms in flat and de Sitter spacetimes

Gravitational radiations of Kerr black hole from warped symmetries J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-17 Jianfei Xu
The warped conformal symmetries have been found in the covariant phase space of a set of non-trivial diffeomorphism near the Kerr black hole horizon. In this paper, we consider the retarded Green’s function and the absorption probability for the scalar and higher spin perturbations on a generic non-extreme Kerr black hole background, and perform their holographic calculations in terms of the warped

Mixed boundary conditions and double-trace like deformations in Celestial holography and Wedge-like holography J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-17 Machiko Fukada, Akihiro Miyata
According to the AdS/CFT dictionary, adding a relevant double-trace deformation f ∫ O2 to a holographic CFT action is dual to imposing mixed Neumann/Dirichlet boundary conditions for the field dual to O in AdS. We observed similar behaviour in codimension-two flat space holographies. We consider deformations of boundary conditions in flat spacetimes under flat space codimension-two holographies, Celestial

An optimized basis for hadronic light-by-light scattering J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-17 Martin Hoferichter, Peter Stoffer, Maximilian Zillinger
We present a new basis for the hadronic light-by-light (HLbL) tensor that is optimized for the evaluation of narrow-resonance contributions to HLbL scattering in the anomalous magnetic moment of the muon. As main advantage, kinematic singularities are manifestly absent for pseudoscalar, scalar, and axial-vector states, while the remaining singularities for tensor resonances are minimized, even avoided

Solvable limit of ETH matrix model for double-scaled SYK J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-17 Kazumi Okuyama, Takao Suyama
We study the two-matrix model for double-scaled SYK model, called ETH matrix model introduced by Jafferis et al. [arXiv:2209.02131]. If we set the parameters qA, qB of this model to zero, the potential of this two-matrix model is given by the Gaussian terms and the q-commutator squared interaction. We find that this model is solvable in the large N limit and we explicitly construct the planar one-

Broad sterile neutrinos & the reactor/gallium tension J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-17 Hannah Banks, Kevin J. Kelly, Matthew McCullough, Tao Zhou
Significant evidence exists for the apparent disappearance of electron-type neutrinos in radioactive source experiments. Yet, interpreted within the standard ‘3+1 sterile neutrino scenario’, precision short-baseline measurements of electron antineutrinos from nuclear reactors strongly disagree with these results. Recently, it has been demonstrated that allowing for a finite wavepacket size for the

A study on spontaneously translational symmetry breaking in the excited states of holographic superconductor J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-17 Qian Xiang, Li Zhao, Tie-Feng Fang, Yong-Qiang Wang
We revisit HHH model [1] and extend the ansatz of matter fields to being of depending on a spatial dimension except the holographic direction. Despite homogeneous solutions of ground and excited states, especially for the excited states, there also exists solutions where the translational invariance is broken. It is worth mentioning that no periodic sources are assigned to the matter fields, so the

Examination of kt-factorization in a Yukawa theory J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-17 B. Guiot, A. van Hameren
We discuss the upper limit, kmax, of the transverse-momentum integration performed in the kt-factorization formula. Based on explicit calculations in the Yukawa theory and the study of seminal papers, we argue that kmax is equal to the factorization scale μF used to factorize the cross section into an off-shell hard coefficient and a universal factor. There is consequently a relation between kmax and

Double parton distributions with flavor interference from lattice QCD J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-17 Daniel Reitinger, Christian Zimmermann, Markus Diehl, Andreas Schäfer
We study double parton distributions with flavor interference in the nucleon and compare them with previous results for the flavor diagonal case. We investigate both unpolarized and polarized partons. We compare our lattice results with those obtained from the simple description of the proton in terms of an SU(6) symmetric three-quark wave function and find that this description fails for both flavor

Doubled Hilbert space in double-scaled SYK J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-17 Kazumi Okuyama
We consider matter correlators in the double-scaled SYK (DSSYK) model. It turns out that matter correlators have a simple expression in terms of the doubled Hilbert space \(\mathcal{H}\otimes \mathcal{H}\), where \(\mathcal{H}\) is the Fock space of q-deformed oscillator (also known as the chord Hilbert space). In this formalism, we find that the operator which counts the intersection of chords should

A study of the SYK2 model with twisted boundary conditions J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-17 Jeff Murugan, Ruach Pillay Slayen, Hendrik J. R. Van Zyl
We study a version of the 2-body Sachdev-Ye-Kitaev (SYK2) model whose complex fermions exhibit twisted boundary conditions on the thermal circle. As we show, this is physically equivalent to coupling the fermions to a 1-dimensional external gauge field A(t). In the latter formulation, the gauge field itself can be thought of as arising from a radial symmetry reduction of a (2 + 1)-dimensional Chern-Simons

No U(1) ‘electric-magnetic’ duality in Einstein gravity J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-17 Ricardo Monteiro
We revisit the question of whether classical general relativity obeys, beyond the linearised order, an analogue of the global U(1) electric-magnetic duality of Maxwell theory, with the Riemann tensor playing the role analogous to the field strength. Following contradictory claims in the literature, we present a simple gauge-invariant argument that the duality does not hold. The duality condition is

Sensitivity of octant of θ23, CP violation and mass hierarchy in NOνA with multinucleon and detector effects J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-17 Paramita Deka, Kalpana Bora
In this work, we investigate how multinucleon enhancement and RPA (Random Phase Approximation) suppression can affect the measurement of three unknown neutrino oscillation parameters — the CP-violating phase δCP, the octant of the atmospheric mixing angle θ23, and the determination of the mass hierarchy, in the appearance channel of the NOνA experiment. We include the presence of the detector effect

Gauged permutation invariant matrix quantum mechanics: path integrals J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-16 Denjoe O’Connor, Sanjaye Ramgoolam
We give a path integral construction of the quantum mechanical partition function for gauged finite groups. Our construction gives the quantization of a system of d, N × N matrices invariant under the adjoint action of the symmetric group SN. The approach is general to any discrete group. For a system of harmonic oscillators, i.e. for the non-interacting case, the partition function is given by the

Dark showers from Z-dark Z′ mixing J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-16 Hsin-Chia Cheng, Xu-Hui Jiang, Lingfeng Li, Ennio Salvioni
We discuss dark shower signals at the LHC from a dark QCD sector, containing GeV-scale dark pions. The portal with the Standard Model is given by the mixing of the Z boson with a dark Z′ coupled to the dark quarks. Both mass and kinetic mixings are included, but the mass mixing is the essential ingredient, as it is the one mediating visible decays of the long-lived dark pions. We focus especially on

Bilocal holography and locality in the bulk J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-16 Robert de Mello Koch, Garreth Kemp, Hendrik J. R. Van Zyl
Bilocal holography provides a constructive approach to the vector model/higher spin gravity duality. It has two ingredients: a change of field variables and a change of space time coordinates. The change of field variables ensures that the loop expansion parameter becomes \( \frac{1}{N} \). The change of coordinates solves the Clebsch-Gordan problem of moving from the tensor product basis (in which

Thermodynamics of the Einstein-Maxwell system J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-16 Shoichiro Miyashita
At first glance, thermodynamic properties of gravity with asymptotically AdS conditions and those with box boundary conditions, where the spatial section of the boundary is a sphere of finite radius, appear similar. Both exhibit a similar phase structure and Hawking-Page phase transition. However, when we introduce a U(1) gauge field to the system, discrepancies in thermodynamic properties between

On the oscillating electric dipole moment induced by axion-fermion couplings J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-12 Luca Di Luzio, Hector Gisbert, Philip Sørensen
It has been recently claimed that the axion coupling to fermions is responsible for an oscillating electric dipole moment (EDM) in the background of axion dark matter. In this work, we re-examine the derivation of this effect. Contrary to previous studies, we point out the physical relevance of an axion boundary term, which is crucial in restoring the axion shift symmetry and drastically affects the

On the breakdown of eikonal approximation and survival of Reggeization in presence of dimension-5 Higgs-gluon coupling J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-12 Michael Fucilla, Maxim A. Nefedov, Alessandro Papa
We consider the one-loop effective vertex for the interaction of a gluon with a Reggeized gluon and a Higgs boson in the infinite-top-mass limit, which is described by a dimension-5 non-renormalizable operator. This vertex enters the calculation of differential cross sections for the forward inclusive production of a Higgs boson in high-energy proton-proton collisions, possibly in association with

Relativistic single-electron wavepacket in quantum electromagnetic fields: quantum coherence, correlations, and the Unruh effect J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-12 Shih-Yuin Lin, Bei-Lok Hu
Conventional formulation of QED since the 50s works very well for stationary states and for scattering problems, but with newly arisen challenges from the 80s on, where real time evolution of particles in a nonequilibrium setting are required, and quantum features such as coherence, dissipation, correlation and entanglement in a system interacting with its quantum field environment are sought after

Anomaly constraints for heterotic strings and supergravity in six dimensions J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-12 Ivano Basile, Giorgio Leone
The landscape of six-dimensional supergravities is dramatically constrained by the cancellation of gauge and gravitational anomalies, but the full extent of its implications has not been uncovered. We explore the cancellation of global anomalies of the Dai-Freed type in this setting with abelian and simply laced gauge groups, finding novel constraints. In particular, we exclude arbitrarily large abelian

Improved Standard-Model prediction for KL → ℓ+ℓ− J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-12 Martin Hoferichter, Bai-Long Hoid, Jacobo Ruiz de Elvira
We present a comprehensive calculation of the KL → γ∗γ∗ form factor in dispersion theory, using input from the leptonic decays KL → ℓ+ℓ−γ, \({K}_{L}\to {{\ell}}_{1}^{+}{{\ell}}_{1}^{-}{{\ell}}_{2}^{+}{{\ell}}_{2}^{-}\), the hadronic mode KL → π+π−γ, the normalization KL → γγ, and the matching to asymptotic constraints. As key result we obtain an improved determination of the long-distance contribution

QCD corrections to the Golden decay channel of the Higgs boson J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-12 Mandeep Kaur, Maguni Mahakhud, Ambresh Shivaji, Xiaoran Zhao
Future colliders aim to provide highly precise experimental measurements of the properties of the Higgs boson. In order to benefit from these precision machines, theoretical errors in the Higgs sector observables have to match at least the experimental uncertainties. The theoretical uncertainties in the Higgs sector observables can be reduced by including missing higher-order terms in their perturbative

Using the effective weak mixing angle as an input parameter in SMEFT J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-12 Anke Biekötter, Benjamin D. Pecjak, Tommy Smith
We implement electroweak renormalisation schemes involving the effective weak mixing angle to NLO in Standard Model Effective Field Theory (SMEFT). After developing the necessary theoretical machinery, we analyse a select set of electroweak precision observables in such input schemes. An attractive feature is that large corrections from top-quark loops appearing in other schemes are absorbed into the

Irreducible representations of the Poincaré group with reflections and two-fold Wigner degeneracy J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-12 Dharam Vir Ahluwalia, G. B. de Gracia, Julio M. Hoff da Silva, Cheng-Yang Lee, B. M. Pimentel
Not all complete set of spinors can be used as expansion coefficients of a quantum field. In fact, Steven Weinberg established the uniqueness of Dirac spinors for this purpose provided: (a) one paid due attention to the multiplicative phases for each of the spinors, and (b) one paired these to creation and annihilation operators in a specific manner. This is implicit in his implementation of the rotational

Is the Euclidean path integral always equal to the thermal partition function? J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-12 D. V. Diakonov
The Euclidean path integral is compared to the thermal (canonical) partition function in curved static space-times. It is shown that if spatial sections are non-compact and there is no Killing horizon, the logarithms of these two quantities differ only by a term proportional to the inverse temperature, that arises from the vacuum energy. When spatial sections are bordered by Killing horizons the Euclidean

A generalized Selberg zeta function for flat space cosmologies J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-12 Arjun Bagchi, Cynthia Keeler, Victoria Martin, Rahul Poddar
Flat space cosmologies (FSCs) are time dependent solutions of three-dimensional (3D) gravity with a vanishing cosmological constant. They can be constructed from a discrete quotient of empty 3D flat spacetime and are also called shifted-boost orbifolds. Using this quotient structure, we build a new and generalized Selberg zeta function for FSCs, and show that it is directly related to the scalar 1-loop

Dark sector glueballs at the LHC J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-12 Austin Batz, Timothy Cohen, David Curtin, Caleb Gemmell, Graham D. Kribs
We study confining dark sectors where the lightest hadrons are glueballs. Such models can provide viable dark matter candidates and appear in some neutral naturalness scenarios. In this work, we introduce a new phenomenological model of dark glueball hadronization inspired by the Lund string model. This enables us to make the most physically-motivated predictions for dark glueball phenomenology at

Revisiting metastable cosmic string breaking J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-12 Akifumi Chitose, Masahiro Ibe, Yuhei Nakayama, Satoshi Shirai, Keiichi Watanabe
Metastable cosmic strings appear in models of new physics with a two-step symmetry breaking G → H → 1, where π1(H) ≠ 0 and π1(G) = 0. They decay via the monopole-antimonopole pair creation inside. Conventionally, the breaking rate has been estimated by an infinitely thin string approximation, which requires a large hierarchy between the symmetry breaking scales. In this paper, we reexamine it by taking

Elastic Kink-Meson scattering J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-12 Jarah Evslin, Hui Liu
In classical field theory, radiation does not reflect off of reflectionless kinks. In quantum field theory, radiation quanta, called mesons, can be reflected. We provide a general analytical formula for the leading order amplitude and probability for the elastic scattering of mesons off of reflectionless quantum kinks. In the case of the Sine-Gordon model we verify that, due to a cancellation of six

Instanton NDA and applications to axion models J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-12 Csaba Csáki, Raffaele Tito D’Agnolo, Eric Kuflik, Maximilian Ruhdorfer
We present a simple set of power counting rules which allows us to easily estimate calculable instanton effects up to \( \mathcal{O} \)(1) factors. We apply the resulting Instanton NDA to examine the effects of small instantons on various axion models. We confirm that mechanisms that increase the axion mass via small instantons generically also lead to an enhancement of misaligned instanton contributions

Demystifying the Emergence Proposal J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-11 Ralph Blumenhagen, Niccolò Cribiori, Aleksandar Gligovic, Antonia Paraskevopoulou
We revisit the Emergence Proposal in the vector multiplet moduli space of type IIA N = 2 supersymmetric string vacua in four dimensions, for which the string tree-level prepotential and the string one-loop correction are exactly known via mirror symmetry. We argue that there exists an exact notion of emergence, according to which these four-dimensional couplings can be computed exactly in any asymptotic

Orbital angular momentum small-x evolution: exact results in the large-Nc limit J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-11 Brandon Manley
We construct an exact solution to the revised small-x orbital angular momentum (OAM) evolution equations derived in [1], based on an earlier work [2]. These equations are derived in the double logarithmic approximation (summing powers of αs ln2(1/x) with αs the strong coupling constant and x the Bjorken x variable) and the large-Nc limit, with Nc the number of quark colors. From our solution, we extract

Tensionless strings on AdS3 orbifolds J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-11 Matthias R. Gaberdiel, Bin Guo, Samir D. Mathur
The bound state of one NS5 brane (wrapped on a 𝕋4) and N NS1-branes has two dual descriptions: its low-energy dynamics is described by the symmetric orbifold of 𝕋4, while the near horizon geometry is captured by string theory on AdS3 × S3 × 𝕋4 with one unit of NS flux. The latter theory is exactly solvable in the hybrid formalism, and this allows one to prove the equivalence of the two descriptions

Evolution of parton distribution functions in the short-distance factorization scheme J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-11 Hervé Dutrieux, Joseph Karpie, Christopher Monahan, Kostas Orginos, Savvas Zafeiropoulos
Lattice QCD offers the possibility of computing parton distributions from first principles, although not in the usual \( \overline{MS} \) factorization scheme. Calculations are therefore matched to \( \overline{MS} \) using a perturbative procedure which is the source of significant uncertainty within the currently accessible kinematics. We present the possibility of computing the z2 evolution of non-singlet

Non-resonant anomaly detection with background extrapolation J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-11 Kehang Bai, Radha Mastandrea, Benjamin Nachman
Complete anomaly detection strategies that are both signal sensitive and compatible with background estimation have largely focused on resonant signals. Non-resonant new physics scenarios are relatively under-explored and may arise from off-shell effects or final states with significant missing energy. In this paper, we extend a class of weakly supervised anomaly detection strategies developed for

Four-dimensional $$\mathcal{N}$$ = 2 superconformal long circular quivers J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-11 M. Beccaria, G.P. Korchemsky
We study four-dimensional \(\mathcal{N}\) = 2 superconformal circular, cyclic symmetric quiver theories which are planar equivalent to \(\mathcal{N}\) = 4 super Yang-Mills. We use localization to compute nonplanar corrections to the free energy and the circular half-BPS Wilson loop in these theories for an arbitrary number of nodes, and examine their behaviour in the limit of long quivers. Exploiting

The QCD axion sum rule J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-11 Belén Gavela, Pablo Quílez, Maria Ramos
We demonstrate that the true QCD axion that solves the strong CP problem can be found in all generality outside the customary standard QCD band, with QCD being the sole source of Peccei-Quinn breaking. The essential reason is that the basis of axion-gluon interactions does not need to coincide with the mass basis. Specifically, we consider the case in which the QCD axion field is not the only singlet

Crossing beyond scattering amplitudes J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-11 Simon Caron-Huot, Mathieu Giroux, Holmfridur S. Hannesdottir, Sebastian Mizera
We find that different asymptotic measurements in quantum field theory can be related to one another through new versions of crossing symmetry. Assuming analyticity, we conjecture generalized crossing relations for multi-particle processes and the corresponding paths of analytic continuation. We prove them to all multiplicity at tree-level in quantum field theory and string theory. We illustrate how

Kerr binary dynamics from minimal coupling and double copy J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-11 Francesco Alessio
We construct a new Yang-Mills Lagrangian based on a notion of minimal coupling that incorporates classical spin effects. The construction relies on the introduction of a new covariant derivative, which we name “classical spin covariant derivative”, that is compatible with the three-point interaction of the \( \sqrt{\textrm{Kerr}} \) solution with the gauge field. The resulting Lagrangian, besides the

Riemann zeros as quantized energies of scattering with impurities J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-11 André LeClair, Giuseppe Mussardo
We construct an integrable physical model of a single particle scattering with impurities spread on a circle. The S-matrices of the scattering with the impurities are such that the quantized energies of this system, coming from the Bethe Ansatz equations, correspond to the imaginary parts of the non-trivial zeros of the the Riemann ζ(s) function along the axis \(\mathfrak{R}\left(s\right)=\frac{1}{2}\)

Superspin chains solutions from 4D Chern-Simons theory J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-10 Y. Boujakhrout, E. H Saidi, R. Ahl Laamara, L. B Drissi
As a generalisation of the correspondence linking 2D integrable systems with 4D Chern-Simons (CS) gauge theory, superspin chains are realized by means of crossing electric and magnetic super line defects in the 4D CS with super gauge symmetry. The oscillator realization of Lax operators solving the RLL relations of integrability is obtained in the gauge theory by extending the notion of Levi decomposition

Sp(6, Z) modular symmetry in flavor structures: quark flavor models and Siegel modular forms for $$\widetilde{\Delta }\left(96\right)$$ J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-10 Shota Kikuchi, Tatsuo Kobayashi, Kaito Nasu, Shohei Takada, Hikaru Uchida
We study an approach to construct Siegel modular forms from Sp(6, Z). Zero-mode wave functions on T6 with magnetic flux background behave Siegel modular forms at the origin. Then T-symmetries partially break depending on the form of background magnetic flux. We study the background such that three T-symmetries TI, TII and TIII as well as the S-symmetry remain. Consequently, we obtain Siegel modular

Bs → μ+μ− in a two-Higgs-doublet model with flavour-changing up-type Yukawa couplings J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-10 Martin S. Lang, Ulrich Nierste
We present a Two-Higgs-Doublet Model in which the structure of the quark Yukawa matrices is governed by three spurions breaking the flavour symmetries of the quark Yukawa sector. The model naturally suppresses flavour-changing neutral current (FCNC) amplitudes in the down-type sector, but permits sizable FCNC couplings in the up sector. We calculate the branching ratio of Bs → μ+μ− to leading and next-to-leading

Euclidean wormholes for individual 2d CFTs J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-10 Jeevan Chandra
We interpret appropriate families of Euclidean wormhole solutions of AdS3 gravity in individual 2d CFTs as replica wormholes described by branching around the time-symmetric apparent horizons of black holes sourced by the backreaction of heavy point particles. These wormholes help describe a rich formalism to coarse grain pure states in 2d CFTs dual to the black hole geometries because the wormhole

Predictive Dirac neutrino spectrum with strong CP solution in SU(5)L × SU(5)R unification J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-10 K.S. Babu, Rabindra N. Mohapatra, Anil Thapa
We develop a grand unified theory of matter and forces based on the gauge symmetry SU(5)L × SU(5)R with parity interchanging the two factor groups. Our main motivation for such a construction is to realize a minimal GUT embedding of left-right symmetric models that provide a parity solution to the strong CP problem without the axion. We show how the gauge couplings unify with an intermediate gauge

Exploring Seiberg-like N-alities with eight supercharges J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-10 Anindya Dey
We show that a large subclass of 3d \( \mathcal{N} \) = 4 quiver gauge theories consisting of unitary and special unitary gauge nodes with only fundamental/bifundamental matter have multiple Seiberg-like IR duals. A generic quiver \( \mathcal{T} \) in this subclass has a non-zero number of balanced special unitary gauge nodes and it is a good theory in the Gaiotto-Witten sense. We refer to this phenomenon

The global B − L symmetry in the flavor-unified SU(N) theories J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-10 Ning Chen, Ying-nan Mao, Zhaolong Teng
We study the origin of the global B − L symmetry in a class of flavor-unified theories with gauge groups of SU(N ≥ 6). In particular, we focus on the SU(8) theory which can minimally embed three-generational SM fermions non-trivially. A reformulation of the third law for the flavor sector proposed by Georgi is useful to manifest the underlying global symmetries. The ’t Hooft anomaly matching and the

Indirect detection of dark matter with (pseudo)-scalar interactions J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-10 Simone Biondini, Julian Bollig, Stefan Vogl
Indirect detection is one of the most powerful methods to search for annihilating dark matter. In this work, we investigate the impact of non-perturbative effects in the indirect detection of dark matter. For this purpose we utilize a minimal model consisting of a fermionic dark matter candidate in the TeV mass range that interacts via scalar- and pseudo-scalar interactions with a massive scalar mediator

Symmetries and covering maps for the minimal tension string on AdS3 × S3 × T4 J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-10 N. M. McStay, R. A. Reid-Edwards
This paper considers a recently-proposed string theory on AdS3 × S3 × T4 with one unit of NS-NS flux (k = 1). We discuss interpretations of the target space, including connections to twistor geometry and a more conventional spacetime interpretation via the Wakimoto representation. We propose an alternative perspective on the role of the Wakimoto formalism in the k = 1 string, for which no large radius

Boosted rotating dyonic strings in Salam-Sezgin model J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-10 Liang Ma, Yi Pang, H. Lü
We show that the bosonic sector of the N = (1, 0), 6D Salam-Sezgin gauged supergravity model possesses a T-duality symmetry upon a circle reduction to D = 5. We then construct a simple magnetic rotating string solution with two equal angular momenta. Applying the T-duality transformation to this solution, we obtain the general boosted rotating dyonic black string solutions whose global structures and

Elliptic deformations of the AdS3 × S3 × T4 string J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-09 Ben Hoare, Ana L. Retore, Fiona K. Seibold
With the aim of investigating the existence of an integrable elliptic deformation of strings on AdS3 × S3 × T4, we compute the tree-level worldsheet S-matrix of the elliptically-deformed bosonic sigma model on AdS3 × S3 in uniform light-cone gauge. The resulting tree-level S-matrix is compatible with the integrability of the model and has interesting features, including a hidden U(1) symmetry not manifest

Hydrodynamization in hybrid Bjorken flow attractors J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-09 Toshali Mitra, Sukrut Mondkar, Ayan Mukhopadhyay, Anton Rebhan, Alexander Soloviev
Hybrid fluid models, consisting of two sectors with more weakly and more strongly self-interacting degrees of freedom coupled consistently as in the semi-holographic framework, have been shown to exhibit an attractor surface for Bjorken flow. Retaining only the simple viscid fluid descriptions of both sectors, we find that, on the attractor surface, the hydrodynamization times of both subsectors decrease

The operator rings of topological symmetric orbifolds and their large N limit J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-05 Sujay K. Ashok, Jan Troost
We compute the structure constants of topological symmetric orbifold theories up to third order in the large N expansion. The leading order structure constants are dominated by topological metric contractions. The first order interactions are single cycles joining while at second order we can have double joining as well as splitting. At third order, single cycle joining obtains genus one contributions

Holographic transport beyond the supergravity approximation J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-05 Alex Buchel, Sera Cremonini, Laura Early
We set up a unified framework to efficiently compute the shear and bulk viscosities of strongly coupled gauge theories with gravitational holographic duals involving higher derivative corrections. We consider both Weyl4 corrections, encoding the finite ’t Hooft coupling corrections of the boundary theory, and Riemann2 corrections, responsible for non-equal central charges c ≠ a of the theory at the

Positivity from Cosmological Correlators J. High Energy Phys. (IF 5.4) Pub Date : 2024-04-05 Daniel Green, Yiwen Huang, Chia-Hsien Shen, Daniel Baumann
Effective field theories in flat space and in anti-de Sitter space are constrained by causality and unitarity, often in the form of positivity bounds. Similar bounds have been harder to demonstrate in cosmological backgrounds, where the roles of unitarity and causality are more obscure. Fortunately, the expansion of the universe ensures that late-time cosmological correlators are effectively classical
