This paper investigates a second-order extension of perfect spin hydrodynamics in a boost-invariant expansion, finding that while spin dynamics feedback constrains polarization configurations, the resulting behavior remains nearly identical to the non-feedback case as long as the spin polarization magnitude stays below unity.
This study utilizes QCD light-cone sum rules to calculate the magnetic moments of tetraquark states, demonstrating that these electromagnetic properties can effectively distinguish between different internal structures and spin-parity configurations despite similar masses.
This paper presents a sensitivity study demonstrating that the CEPC operating at a center-of-mass energy of 360 GeV, with an integrated luminosity of 1.0 ab, has the potential to discover direct stau pair production up to masses of approximately 170 GeV and smuon pair production up to 178 GeV.
This paper presents a combined thermal and coalescence model for heavy-ion collisions in the few-GeV regime that successfully reproduces proton, pion, and deuteron yields but underpredicts the production of H and He nuclei by a factor of two compared to experimental data.
This paper investigates the application range of perfect spin hydrodynamics in both classical and quantum frameworks by analyzing the relationships between spin polarization, particle mass, temperature, and hydrodynamic flow, providing insights crucial for modeling heavy-ion collisions.
This paper reviews recent advancements in spin hydrodynamics, detailing the theoretical framework of perfect spin hydrodynamics through two equivalent approaches, establishing its applicability to late-stage heavy-ion collisions, and discussing near-equilibrium dynamics.
This paper employs a unified broken SU(6) symmetry scheme combined with G-Parity to determine coupling constants for neutron stars containing hyperons and anti-kaon condensates, revealing that the breaking of this symmetry by anti-kaons significantly compromises the stiffening of the equation of state.
This paper presents lattice QCD calculations of the odd Mellin moments of the pion valence-quark generalized parton distribution up to fifth order across a range of skewness values, utilizing boosted pion states and advanced renormalization techniques to extract skewness-dependent moments through polynomiality-constrained fits.
This paper presents the first derivation of the two-loop renormalization-group equation for the nucleon light-cone distribution amplitude, enabling an analytic solution that reveals significant impacts on leading-logarithmic results for nucleon form factors within the hard-collinear factorization framework.
This paper investigates the formation of primordial black holes as dark matter candidates within the Higgs hybrid metric-Palatini framework, demonstrating that enhanced primordial curvature perturbations can lead to a PBH abundance capable of accounting for all or part of the universe's dark matter depending on the coupling constant and e-folds number.
