Polaronic Proton and Diproton Clustering in Neutron-Rich Matter Phys. Lett. B (IF 4.4) Pub Date : 2024-03-09 Hiroyuki Tajima, Hajime Moriya, Wataru Horiuchi, Eiji Nakano, Kei Iida
We show that the strong spin-triplet neutron-proton interaction causes polaronic protons to occur in neutron matter at subnuclear densities and nonzero temperatures. As the neutron density increases, proton spectra exhibit a smooth crossover from a bare impurity to a repulsive polaron branch; this branch coexists with an attractive polaron branch. With the neutron density increased further, the attractive

In this Letter, we investigate the spontaneous transverse polarization of Λ hyperons produced in unpolarized collisions inside a jet, by adopting a TMD approach where transverse momentum effects are included only in the fragmentation process. We will present predictions based on the parametrizations of the Λ polarizing fragmentation function as extracted from fits to Belle data. These estimates will

W-representations for multi-character partition functions and their β-deformations Phys. Lett. B (IF 4.4) Pub Date : 2024-03-08 Lu-Yao Wang, V. Mishnyakov, A. Popolitov, Fan Liu, Rui Wang
In this letter we continue the development of -representations. We propose several generalizations of the known models, such as the hypergeometric Hurwitz -functions. We construct -representations for multi-character expansions, which involve a generic number of sets of time variables. We propose integral representations for such kind of partition functions which are given by tensor models and multi-matrix

Utilizing a quark model characterized by parameters that effectively replicate the masses of ground state hadrons, we illustrate that or diquarks exhibit greater compactness in comparison to diquarks. Concretely, the binding energy of the diquark - defined as the diquark's mass minus the combined masses of its individual quarks - is found to be stronger than that of the diquark. This heightened attraction

Shadows and photon rings of a quantum black hole Phys. Lett. B (IF 4.4) Pub Date : 2024-03-07 Jing-Peng Ye, Zhi-Qing He, Ai-Xu Zhou, Zi-Yang Huang, Jia-Hui Huang
Recently, a black hole model in loop quantum gravity has been proposed by Lewandowski, Ma, Yang and Zhang (Phys. Rev. Lett. , 101501 (2023)). The metric tensor of the quantum black hole (QBH) is a suitably modified Schwarzschild one. In this paper, we calculate the radius of the circular null geodesic (light ring) and obtain the linear approximation of it with respect to the quantum correction parameter

A positive parity sequence of transitions has been identified above state ( keV) in Sb through in-beam ray spectroscopic technique. Rotational features of this sequence are found similar to a low- decoupled band. Observation of this newly identified low- decoupled band, along with the earlier reported strongly coupled high- band in this nucleus, provides the first experimental evidence for prolate-oblate

Mass density vs. energy density at cosmological scales Phys. Lett. B (IF 4.4) Pub Date : 2024-03-07 Maxim Eingorn, Ezgi Yilmaz, A. Emrah Yükselci, Alexander Zhuk
In the presence of the gravitational field, the energy density of matter no longer coincides with its mass density. A discrepancy exists, of course, also between the associated power spectra. Within the Λ CDM model, we derive a formula that relates the power spectrum of the energy density to that of the mass density and test it with the help of N-body simulations run in comoving boxes of 2.816 Gpc/

We solve for the -meson's wave functions from a light-front QCD Hamiltonian determined for its constituent quark-antiquark and quark-antiquark-gluon Fock components, with a three-dimensional confinement using basis light-front quantization. From this, we obtain the leading-twist valence quark's parton distribution functions and transverse momentum-dependent parton distributions inside the -meson. These

Spallation and fragmentation reactions at incident energies above the Fermi momentum are considered to be the main mechanism for the production of neutron-rich nuclei at worldwide nuclear physics facilities, such as RIBF, FRIB, and GSI-FAIR. Although it is widely known that dynamical reaction models give a rather good prediction of cross sections for nuclear residues produced in spallation and fragmentation

Constraints on pseudo-Dirac neutrinos using high-energy neutrinos from NGC 1068 Phys. Lett. B (IF 4.4) Pub Date : 2024-03-06 Thomas Rink, Manibrata Sen
Neutrinos can be pseudo-Dirac in Nature - they can be Majorana fermions while behaving effectively as Dirac fermions. Such scenarios predict active-sterile neutrino oscillations driven by a tiny mass-squared difference , which is an outcome of soft lepton number violation. Oscillations due to tiny can only take place over astrophysical baselines and hence are not accessible in terrestrial neutrino

In view of recent interest in high-frequency detectors, broad features of gravitational wave signals from phase transitions taking place soon after inflation are summarized. The influence of the matter domination era that follows the slow-roll stage is quantified in terms of two equilibration rates. Turning to the highest-frequency part of the spectrum, we show how it is constrained by the fact that

Cosmic acceleration in entropic cosmology Phys. Lett. B (IF 4.4) Pub Date : 2024-03-04 J. Chagoya, I. Díaz-Saldaña, J.C. López-Domínguez, M. Sabido
In this paper we study the viability of an entropic cosmological model. The effects of entropic gravity are derived from a modified entropy-area relationship with a volumetric entropy term. This model describes a late time limit cosmic acceleration, whose origin is related to a volumetric term in the entropy. Moreover, we analyze the phenomenological implications of the entropic model using the Supernovae

We perform a systematic study of the electromagnetic properties of exotic states to shed light on their nature, which is still controversial and not fully understood. The magnetic dipole and higher multipole moments of a hadronic state are as fundamental a dynamical quantity as its mass, and they contain valuable information about the deep structure underlying it.

This work provides the first combined analysis of low-energy pΛ scattering, considering both cross section and correlation data. The obtained results establish the most stringent constraints to date on the two-body pΛ interaction, pointing to a weaker attraction than so far accepted. The best set of scattering lengths for the spin singlet and triplet are found to range from to fm. With a chiral NY

The principle of multi-critical-points (PMCP) may be a convincing approach to determine the emerging parameter values in different kinds of beyond-standard-model (BSM) models. This could certainly be applied to solve the problem of undetermined new parameters in the ALP-Higgs interaction models. In this paper, we apply this principle to such model and investigate whether there are suitable solutions

We attempt to answer whether Birkhoff's theorem (BT) is valid in the Einstein-Aether (EA) theory. The BT states that any spherically symmetric solution of the vacuum field equations must be static, unique, and asymptotically flat. For a general spherically symmetric metric with metric functions &, and aether components &, we prove the conditions for the staticity of spacetime using two different methods

We establish simple formulae for computing Finkelstein–Rubinstein signs for Skyrme fields generated in two ways: from instanton ADHM data, and from rational maps. This may be used to compute homotopy classes of general loops in the configuration spaces of skyrmions, and as a result provide a useful tool for a quantum treatment beyond rigid-body quantisation of skyrmions.

The bound on the proton lifetime is one of a small handful of observations that constrains physics not far from the Planck scale. This calls for a calculation of the proton lifetime in quantum gravity. Here, we calculate how quantum fluctuations of the metric impact four-fermion interactions which mediate proton decay. We find that quantum gravity lowers the scaling dimension of the four-fermion interaction

Quantum binding energies in the Skyrme model Phys. Lett. B (IF 4.4) Pub Date : 2024-02-15 Sven Bjarke Gudnason, Chris Halcrow
A major problem in the Skyrme model is that the binding energy of skyrmions, which model nuclei, is too high by an order of magnitude. We show that the most popular solution to this problem, to construct models with zero classical binding energy, still produces large binding energies when spin energy is included. We argue that it is thus necessary to include quantum effects. We calculate the binding

The quenching of light and heavy flavor hadrons in relativistic heavy-ion collisions probes the color and flavor dependences of parton energy loss through a color-deconfined quark-gluon plasma (QGP), and thus offers an important test of QCD-based calculation at extremely high density and temperature. By combining a next-to-leading order perturbative QCD calculation of parton production, a general ansatz

Entropy from entangled parton states and high-energy scattering behavior Phys. Lett. B (IF 4.4) Pub Date : 2024-02-08 Hans Günter Dosch, Guy F. de Téramond, Stanley J. Brodsky
The relation between the gluon density in a hadron and entanglement entropy can shed a new light on the high energy scattering behavior of hadrons. Using the holographic light-front QCD framework the growth above the classical geometric cross section is directly related to the increase of the internal quantum entropy from the entangled parton distribution in hadrons. A rather consistent picture emerges

Two-loop corrections to the Carroll-Field-Jackiw term in a CPT-odd Lorentz-violating scalar QED Phys. Lett. B (IF 4.4) Pub Date : 2024-02-07 A.C. Lehum, J.R. Nascimento, A.Yu. Petrov
In this study, we systematically calculate one-loop corrections to the Lorentz-violating vertices within the framework of CPT-odd Quantum Electrodynamics, encompassing scalar and photon fields in arbitrary gauge. Additionally, we ascertain the finite two-loop corrections to the Carroll-Field-Jackiw term. Furthermore, we analyze the UV divergent component of the two-loop Lorentz-violating correction

Machine learning Sasakian and G2 topology on contact Calabi-Yau 7-manifolds Phys. Lett. B (IF 4.4) Pub Date : 2024-02-07 Daattavya Aggarwal, Yang-Hui He, Elli Heyes, Edward Hirst, Henrique N. Sá Earp, Tomás S.R. Silva
We propose a machine learning approach to study topological quantities related to the Sasakian and -geometries of contact Calabi-Yau 7-manifolds. Specifically, we compute datasets for certain Sasakian Hodge numbers and for the Crowley-Nördstrom invariant of the natural -structure of the 7-dimensional link of a weighted projective Calabi-Yau 3-fold hypersurface singularity, for 7549 of the 7555 possible
