We have used the parton and hadron cascade model PACIAE together with the Dynamically Constrained Phase-space Coalescence model (DCPC) to study the Tcs0*(2870)0 production in pp collision at s = 7 TeV, following the LHCb observation of Tcs0*(2870)0 in the B−→D−D0KS0 decays in pp collisions at s = 7, 8, and 13 TeV [PRL 134(2025)101901]. The final hadronic states of the pp collisions at s = 7 TeV are

Quantum computing is emerging as a promising tool in nuclear physics. However, the cost of encoding fermionic operators hampers the application of algorithms in current noisy quantum devices. In this work, we analyze an encoding scheme based on pairing nucleon modes. This approach significantly reduces the complexity of the encoding, while maintaining a high accuracy for the ground states of semimagic

This Letter reports the observation of W+W−γ triboson production in 140 fb−1 of data collected by the ATLAS detector from proton–proton collisions at a centre-of-mass energy of s = 13 TeV at the LHC. Events with an opposite-charge eμ pair, a high transverse-momentum photon, and significant missing transverse momentum are considered. The observed (expected) significance of the signal is 5.9 (6.0) standard

The relative correlation between the magnitudes of elliptic flow (v2) and triangular flow (v3) has been accurately measured in nucleus-nucleus collisions at the LHC collider. As a function of the centrality of the collision, it changes sign and varies non-monotonically. We show that this is naturally explained by two combined effects. The first effect is a skewness in initial-state fluctuations, which

We report the first nucleon gluon parton distribution function (PDF) using Large-Momentum Effective Theory (LaMET). We focus on the gluon operator which was demonstrated to have the best signal-to-noise in the previous attempt [1] in computing gluon PDFs using LaMET. We compute the corresponding Wilson coefficients needed for the hybrid-renormalized matrix elements and the matching kernel to convert

We obtain inequivalent classical r-matrices of the osp(1|2) Lie superalgebra as real solutions of the graded (modified) classical Yang-Baxter equation, in such a way that the corresponding automorphism transformation is employed. Then, Yang-Baxter deformations of the Wess-Zumino-Witten model based on the OSP(1|2) Lie supergroup are specified by super skew-symmetric classical r-matrices. In this regard

Low-, medium-, and high-spin states in 119Sb were populated using the reaction 116Cd(7Li, 4n) at beam energies of 34, 42, and 50 MeV, respectively. A pair of nearly degenerate ΔI=1 doublet, two ΔI=1, and two ΔI=2 bands as well as a number of irregular levels have been observed. These structures are interpreted as chiral, electric, magnetic, and anti-magnetic rotations as well as noncollective structure

Gravitational waves sourced by amplified scalar perturbations are a common prediction across a wide range of cosmological models. These scalar curvature fluctuations are inherently nonlinear and typically non-Gaussian. We argue that the effects of non-Gaussianity may not always be adequately captured by an expansion around a Gaussian field, expressed through nonlinear parameters such as fNL. As a consequence

We formulate an argument, based on the use of the action-angle variables and the Bohr-Sommerfeld quantization rule, to the effect that if there exists the smallest possible non-zero area, there also exists, for massive particles, the largest possible observable speed, which is a bit less than the speed of light.

Thermoelectric phenomena are traditionally associated with the interconversion of thermal and electrical energy in many-body systems. In the context of high-temperature quantum chromodynamics (QCD) matter produced in relativistic heavy-ion collisions, thermoelectric responses can provide insight into the evolving microscopic dynamics and the redistribution of effective degrees of freedom across the

This Letter addresses the contribution from the light u, d, s quarks to the amplitudes for the decay modes of the Brout-Englert-Higgs scalar boson H into two photons (H → γγ) or to a photon and a neutral weak gauge boson (H → γZ), taking into account the non-perturbative aspects of QCD. Contrary to a recent claim, the contribution from the light quarks does not vanish. Rather, it is shown that, in

We investigate Power-Law Plateau (PLP) inflation in standard gravity and its consistency with ACT DR6 data. While many inflationary models, including the Starobinsky inflation, are disfavored by ACT observations, the PLP potential remains viable across a broad range of its parameters. Then, the dynamics of the reheating phase are investigated, with a primary focus on the reheating temperature and its

In this article, the vector, axial vector and tensor form factors of Bc to D-wave charmonia ψJ (J=1,2,3) and ηc2 are analyzed within the framework of three-point QCD sum rules. With the predicted vector and axial vector form factors, we study the decay widths and branching ratios of semileptonic decays Bc→ψJlνl¯ and Bc→ηc2lνl¯. Our results indicate that the semileptonic decay branching ratios of Bc

Under the assumption that the various evidences of a ‘95 GeV’ excess, seen in data at the Large Electron Positron (LEP) collider as well as the Large Hadron Collider (LHC), correspond to actual signals of new physics Beyond the Standard Model (BSM), we characterise the underlying particle explaining these anomalies in terms of its Charge/Parity (CP) quantum numbers. In doing so, we use χ2 fits to test

A state-of-the-art microscopic global nucleon-nucleus optical potential has been developed by Whitehead, Lim, and Holt (WLH) within the framework of many-body perturbation theory, incorporating realistic nuclear interactions derived from chiral effective field theory. Given its potentially greater predictive power for reactions involving exotic isotopes, we apply it to the calculations of astrophysical

A central goal in the study of heavy-flavour production is to determine the interaction strength between Heavy Quarks (HQs) and the Quark-Gluon Plasma (QGP), quantified by the spatial diffusion coefficient Ds(T). Recent lattice QCD (lQCD) results with dynamical fermions suggest a remarkably low value of 2πTDs ≈ 1 at T=Tc for charm quarks - significantly lower than both quenched QCD estimates and most

The structure of the 2243Ti21 nucleus has been explored employing correlations between delayed and prompt γ rays, leading to a substantial extension of its positive-parity yrast band up to 25/2+. New states were were identified using the isomer-tagging technique together with γ−γ coincidences and were compared to the analogue states in the mirror nucleus 2143Sc22. The Mirror Energy Differences (MED)

We use the Tomonaga–Schwinger (TS) formulation of quantum field theory to determine when state-dependent additions to the local Hamiltonian density (i.e., modifications to linear Schrödinger evolution) violate relativistic covariance. We derive new operator integrability conditions required for foliation independence, including the Fréchet derivative terms that arise from state-dependence. Nonlinear

We study the effect on the primordial tensor power spectrum of varying the number of e-folds during slow-roll inflation in Loop Quantum Cosmology with a Starobinsky potential. Using the hybrid quantization approach, we derive the effective mass governing tensor mode evolution. The choice of vacuum state is crucial, especially since the preinflationary phase predicted by Loop Quantum Cosmology invalidates

We explore the potential to detect the U(1)Lμ−Lτ model featuring triplet scalars Δ at the μTRISTAN collider. The new gauge boson Z′, arising from the spontaneous breaking of U(1)Lμ−Lτ, can exhibit maximal flavor changing interactions under the exchange symmetry, while Δ mediates the flavor conserving interactions. The absence of muon (g−2)μ can be explained by interference effects arising from opposite

Knowledge of the slope of nuclear symmetry energy at the saturation density L is crucial for guiding the extrapolation of the symmetry energy to both lower and higher densities, yet its value remains with significant uncertainty. A promising probe for constraining L is the difference in mirror pair root-mean-square (rms) charge radii ΔRch. However, the ΔRch data are scarce due to the difficulty in

Baryogenesis refers to the physical process responsible for generating the observed baryon asymmetry in the early universe. The presence of a nonzero baryon number density suggests a surplus of matter over antimatter. In this study, a novel approach is proposed to verify the direct consequences of late-time observations on gravitational baryogenesis. The incorporation of two key data sets, DESI and

It has recently been proved that, for constant density stars, there is a critical value Λ*=1 for the dimensionless density parameter Λ ≡ 4πR2ρmax of the star above which the asymptotically measured travel time Ts along a semi-circular trajectory that connects two antipodal points on the surface of the star is shorter than the travel time Tc along the (shorter) straight-line trajectory that connects

We discuss the conversion mechanism from scalar field to gravitational waves in magnetic background in f(R) gravity minimal coupled to the Maxwell electrodynamics. Applying the conversion in early universe with primordial magnetic field and the neutron star with strong magnetosphere, the generated gravitational waves, converted from the scalar field, exhibit distinct power spectra which can be potentially

Proton-rich nuclei beyond the proton drip line are of great interest in nuclear structure physics, due to exotic phenomena such as proton emissions and the Thomas-Ehrman shift (TES). In this work, we employ the Gamow shell model (GSM) to investigate the structure and decay of 20Si, a candidate for six-proton (6p) emission, which can be produced via two-neutron knockout from the drip line nucleus 22Si

The search for lepton flavor violation (LFV) is a powerful probe to look for new physics beyond the Standard Model. We explored the possibility of searches for LFV Z boson couplings to electron and muon pairs at the upcoming electron-proton colliders, namely the Large Hadron Electron Collider (LHeC) and the Future Circular lepton-hadron Collider (FCC-eh). We employed the study via a single muon plus

We argue that the renormalizability of interacting quantum field theory on the curved-space background with an additional external antisymmetric tensor (two-form) field requires nonminimal interaction of the antisymmetric field with quantum fermions and scalars. The situation is qualitatively similar to the metric and torsion background. In both cases, one can explore the renormalization group running

The intense photon fluxes from relativistic nuclei provide an opportunity to study photonuclear interactions in ultraperipheral collisions. In particular, it allows for the investigations of excited, light-flavour vector mesons. The measurement of coherently photoproduced π+π−π+π− final states in ultraperipheral Pb–Pb collisions at sNN=5.02 TeV is presented for the first time. The cross section, dσ/dy

We construct a new rotating solution of Einstein’s theory in vacuum by exploiting the Lie point symmetries of the field equations in the complex potential formalism of Ernst. In particular, we perform a discrete symmetry transformation, known as inversion, of the gravitational potential associated with the Kerr metric. The resulting metric describes a rotating generalization of the Schwarzschild–Levi-Civita

The recent report by the CMS Collaboration on the excess of top and anti-top pair production is examined with regard to the improvement of vacuum stability under two simple scenarios: one with the existence of toponium (ηt), and the other with an additional elementary field (Ψ). In both cases, the values of each coupling constant are restricted by the Multicritical Point Principle (MPP).

In this work, we present a new analysis for f(R, T) gravity by exploring the energy momentum tensor. We demonstrate that f(R, T) gravity with the form f(R,T)=R+2κ2λT−2Λ is equivalent to Running Vacuum Energy (RVE), which interacts with the components of the cosmic fluid, namely dark matter and radiation. Interestingly, the form of such interaction is inferred from the non-conservation of the stress

Motivated by closed string perturbation theory arguments by S. Shenker, we consider non-perturbative effects of characteristic strength O(e−1/gs), with gs the closed string coupling constant, in supersymmetric critical heterotic string theories. We argue that in 10D such effects arise from heterotic “D-instantons,” i.e. heterotic disk diagrams, whose existence relies on a non-trivial interplay between

In this paper, we study the motion of a massless, chargeless particle in Schwarzschild-de Sitter spacetime, revealing exponential radial growth and potential chaos in an integrable system. Poincaré sections show regular Kolmogorov–Arnold–Moser (KAM) tori when black hole and cosmological horizons are distant, but distortions and chaos emerge as they converge. As the horizons coincide, the Poincaré sections

Neutron skins of neutron-rich nuclei connect nuclei with the matter in neutron stars. High-precision measurements of nuclear charge densities to extract higher-order moments are proposed to be sensitive to neutron radii and skin thicknesses. We investigate the charge density of 48Ca and 208Pb, leading candidates for such studies, with ab initio nuclear structure calculations. We find strong correlations

The global symmetries in maximally supersymmetric theories of gravity in d ≥ 4 are shown to have a universal form in light-cone superspace. The procedure for deriving an all order expression for the d=4 case is also discussed.

The discoveries of the hidden-charm Pc pentaquarks by the LHCb Collaboration have been not confirmed by other experiments yet. It is desirable to investigate the feasibility of observing them in other experiments. We present an order-of-magnitude estimate of the cross section of the e+e−→J/ψpp¯ process, where the hidden-charm pentaquarks may be searched for, and find it to be of O(4fb) when the e+e−

We present an ab initio study of nuclear structure in the island of inversion around neutron number N=20, using multishell effective Hamiltonians derived from the valence-space in-medium similarity renormalization group approach combined with the quantum-number projected generator coordinate method. By progressively expanding the valence space from the sd shell to the intermediate sdf7/2p3/2 space
