Abstract

The most recent development of the quark-meson coupling (QMC) model, in which the effect of the mean scalar field in-medium on the hyperfine interaction is also included self-consistently, is used to compute the properties of hypernuclei. The calculations for Lambda and Xi hypernuclei are of comparable quality to earlier QMC results without the additional parameter needed there. Even more significantly, the additional repulsion associated with the increased hyperfine interaction in-medium completely changes the predictions for Sigma hypernuclei. Whereas in the earlier work they were bound by an amount similar to Lambda hypernuclei, here they are unbound, in qualitative agreement with the experimental absence of such states. The equivalent non-relativistic potential felt by the Sigma is repulsive inside the nuclear interior and weakly attractive in the nuclear surface, as suggested by the analysis of Sigma-atoms.

B Meson Decays in the Covariant Confined Quark Model

Stanislav Dubnicka, Anna Z. Dubnickova, Mikhail A. Ivanov, Andrej Liptaj

Summary: The aim of this text is to present the covariant confined quark model (CCQM) and review its applications in the decays of B mesons. We do so in the context of existing experimental measurements and theoretical results of other authors, which we also review. The physics principles are, in detail, exposed for the CCQM; the other results (theoretical and experimental) are surveyed in an enumerative way with comments.

Double-Strangeness Molecular-Type Pentaquarks from Coupled-Channel Dynamics

J. A. Marse-Valera, V. K. Magas, A. Ramos

Summary: The existence of pentaquarks with strangeness content zero and one is a significant discovery in recent years in the field of hadron physics. These states can be explained as hadronic molecules and were predicted before their discovery based on a model using unitarized meson-baryon amplitudes obtained from vector meson exchange interactions. Contrary to previous beliefs, this model also predicts the existence of pentaquarks with double strangeness at approximately 4500 and 4600 MeV, which are generated through a specific and unique mechanism involving a strong coupling between the two heaviest meson-baryon states.

Cross sections for inelastic K plus φ scattering

Yi-Hao Pan, Xiao-Ming Xu

Summary: This study investigates the reactions K phi -> pi K, rho K, pi K*, and rho K* using the Born approximation and considering quark-antiquark annihilation and creation. Transition amplitudes are obtained by expanding the relative-motion wave functions of initial and final mesons in spherical harmonics, ensuring the conservation of parity and total angular momentum. Unpolarized cross sections, which are calculated from the transition amplitudes, exhibit a significant temperature dependence. While the cross sections for K phi -> rho K, K phi -> pi K*, and K phi -> rho K* may reach the millibarn scale, the cross section for K phi -> K pi is small.

Effects of the QCD critical point on the spectra and flow coefficients of hadrons

Sushant K. Singh, Jan -e Alam

Summary: The space-time evolution of the hot and dense fireball of quarks and gluons produced in ultrarelativistic heavy-ion collisions at nonzero baryonic chemical potential and temperature has been studied. A numerical code has been developed to solve the relativistic viscous causal hydrodynamics in (3 + 1) dimensions with the inclusion of QCD critical point through the equation of state and scaling behavior of transport coefficients. The effects of the QCD critical point on the observables, such as the transverse momentum spectra, directed and elliptic flow coefficients of pions and protons, are largely obliterated by the integration over the entire space-time history of the fireball for the event averaged initial conditions considered here.

Effect of momentum anisotropy on quark matter in the quark-meson model

He-Xia Zhang, Ben-Wei Zhang

Summary: The study investigates the chiral phase structure of quark matter with momentum-space anisotropy in the 2+1 flavor quark-meson model. The critical endpoint location and chiral phase diagram are significantly affected by the anisotropy parameter xi. Additionally, an increase in xi leads to a shift in the critical endpoint to lower temperatures and higher quark chemical potentials, hindering the restoration of chiral symmetry.

Summary: Hadron spectroscopy is essential for understanding the dynamics of the strong interaction, especially in light hadron systems where experimental data play a crucial role in constraining theoretical models. The Beijing Spectrometer Experiment has been studying light meson spectroscopy for nearly three decades, providing unique opportunities to search for exotic states and conduct systematic studies of conventional light mesons.

Ab initio calculation of charge-symmetry breaking in A=7 and 8 A hypernuclei

Hoai Le, Johann Haidenbauer, Ulf-G. Meissner, Andreas Nogga

Summary: This study investigates the separation energies of the isospin triplet 7A He, 7A Li*, 7A Be, and the T = 1/2 doublet 8A Li, 8A Be using the no-core shell model. The calculations are based on a hyperon-nucleon potential derived from chiral effective field theory. The results show that the predicted charge-symmetry breaking (CSB) in the A = 7 systems agrees with the empirical binding energies within experimental uncertainty, while in the A = 8 doublet, the computed CSB is slightly larger than the experimental value.

Coupling Hadron-Hadron Thresholds within a Chiral Quark Model Approach

Pablo G. Ortega, David R. Entem

Summary: Heavy hadron spectroscopy was well understood in the naive quark model until the discovery of X(3872) in 2003, which revealed the limitations of the simple model and the need to consider coupling to two-meson states for a better understanding of excited states of heavy mesons.

Chiral phase transitions of helical matter

Shen-Song Wan, Gianluca Giuliani, Marco Ruggieri

Summary: The study focuses on the thermodynamics of helical matter, specifically quark matter with a net helicity nH in equilibrium. Interactions are modeled using the renormalized quark-meson model with two quark flavors, with helical density described through grand-canonical ensemble formalism. The research also explores the transitions from normal quark matter and hadron gas to helical matter, drawing the phase diagram at zero temperature, and investigates the impact of rigid rotation on helical matter, particularly on the fluctuations of nH, which are enhanced by the rotation.

Effect of the pion field on the distributions of pressure and shear in the proton

Shiryo Owa, A. W. Thomas, X. G. Wang

Summary: In this study, the pressure and shear distributions in the proton are calculated using a model with confined quarks supplemented by the pion field required by chiral symmetry. The incorporation of the pion contributions explains the long-range distributions, which are in agreement with experimentally extracted quark contributions. The results of the model are also compared with lattice QCD results at unphysically large quark mass.

Sensitivity of Parity-Violating Electron Scattering to a Dark Photon

A. W. Thomas, X. G. Wang, A. G. Williams

Summary: The paper examines the sensitivity of the parity-violating electron scattering asymmetry to the properties of a dark photon, and explores its impact on both elastic and deep-inelastic scattering. With recent advancements in experimental capabilities, there is potential for discovering new physics through PVES, as well as a potential for altering our understanding of atomic nuclei, neutron stars, and parton distribution functions through the existence of a dark photon.

Novel neutron decay mode inside neutron stars

Wasif Husain, Anthony W. Thomas

Summary: This study explores the possibility of neutrons decaying into dark matter to solve the neutron lifetime puzzle, and examines its consequences for neutron star properties. The study suggests that a strong repulsive force between dark matter particles is not necessary to satisfy the constraints on neutron star mass and tidal deformability. It proposes the existence of hot dark matter at the core of neutron stars and investigates a possible mechanism of dark matter cooling.

Dark photon effect on the rare kaon decay K-L -> pi(0) nu(nu)over-bar

Xuan-Gong Wang, A. W. Thomas

Summary: We analyze the impact of a dark photon on the rare kaon decay K-L -> pi(0) nu(nu) over bar. The couplings between the dark photon and standard model particles are derived explicitly in terms of the dark photon mass and mixing parameter. We find that the dark photon correction to the standard model branching ratio Br(K-L -> pi(0) nu(nu) over bar) is no more than a few percent in the relevant region.

Constraining Dark Boson Decay Using Neutron Stars

Wasif Husain, Dipan Sengupta, A. W. Thomas

Summary: Inspired by the anomaly in neutron lifetime, this study investigates its effects inside neutron stars. Firstly, the viability of the neutron decay hypothesis proposed by Fornal and Grinstein within neutron stars is assessed, considering the equation of state and compatibility with observed properties. Subsequently, the constraint information on neutron star cooling, in relation to the decay rate of the dark boson into standard model particles, is examined within the context of various beyond the standard model (BSM) ideas.

Dense nuclear matter with phenomenological short distance repulsion

Jesper Leong, Theo F. Motta, Anthony W. Thomas, P. A. M. Guichon

Summary: The equation of state generated by the quark-meson coupling model incorporates the possibility of new short distance physics within neutron star cores. The contribution of this new physics to the energy density is proportional to the overlap between the quark cores of the baryons involved. By maintaining the properties of symmetric nuclear matter at saturation density and including an incompressibility compatible with data on giant monopole resonances, neutron stars with a maximum mass M-max > 2.1M(?) can be sustained even with the inclusion of hyperons.

Recoil proton polarization: A new discriminative observable for deeply virtual Compton scattering

Olga Bessidskaia Bylund, Maxime Defurne, Pierre A. M. Guichon Irfu

Summary: Generalized parton distributions describe the correlations between momentum and position of quarks and gluons in a nucleon. They can be constrained by measuring photon leptoproduction observables. The polarization of the recoil proton is introduced as a new DVCS observable that is highly sensitive to E, and it can be studied experimentally at a high-luminosity facility like Jefferson Lab.

Curtis D. Abell, Derek B. Leinweber, Anthony W. Thomas, Jia-Jun Wu

Summary: The process of renormalization in nonperturbative Hamiltonian effective field theory (HEFT) is examined in the Delta-resonance scattering channel. HEFT provides a bridge between the infinite-volume scattering data of experiment and the finite-volume spectrum of energy eigenstates in lattice QCD, and examines the sensitivity of the finite-volume spectrum and state composition on the regulator.

Summary: In this study, we investigate the near-threshold meson photoproduction from protons and nuclei and explore the possibility of observing non-strange hidden-bottom pentaquark states through differential observables. We calculate the excitation functions and energy/momentum distributions for different production processes and propose that future experiments at high-luminosity electron-ion colliders could provide evidence for the existence of these hidden-bottom pentaquark resonances.

Y. G. Yao, X. Y. Wu, H. Mei

Summary: This study presents a microscopic investigation of the electromagnetic properties of the low-lying states of single-A hypernucleus 9ABe using the HyperGCM method based on covariant density functional theory. The results are compared to those of a particle-rotor model (PRM) and show close agreement. It is found that the electric quadrupole transition strengths are more sensitive to the coupling strengths of the AN interaction than the magnetic moments and M 1 transition strengths.
