This paper demonstrates that the General Next-to-Minimal Supersymmetric Standard Model (GNMSSM) can explain the LUX-ZEPLIN high-recoil event through Higgsino-Singlino mixing, which enables the necessary sub-MeV neutralino mass splitting and correct relic abundance with TeV-scale gauginos, thereby avoiding the ultra-heavy gaugino masses typically required in the MSSM.
This paper reveals that in magnetized two-flavor color-superconducting quark matter, Landau quantization suppresses conventional Fermi-surface contributions to the Meissner effect, leading to a topologically constrained response governed by the quantum metric of the lowest Landau level that scales with the pairing gap rather than the chemical potential, with potential implications for magnetar oscillations.
This paper presents an EOS-driven extension of the NSCool thermal evolution code that unifies the treatment of nucleonic, hyperonic, and quark degrees of freedom within a single workflow, incorporating updated neutrino emissivity and heat capacity calculations for mixed-phase compact stars.
This paper demonstrates that -factorization in the Color Glass Condensate represents only the zeroth order of a systematic gradient expansion, revealing that higher-order corrections involving transverse derivatives of source distributions generate intrinsic initial-state momentum anisotropies and a more complete energy-momentum tensor that are missed by leading-order approximations.
This paper reviews the theoretical foundations and recent applications of the gradient flow as a gauge- and O(4)-invariant ultraviolet regulator in QCD, highlighting its role in bridging non-perturbative lattice calculations with perturbative operator-product expansions for observables like parton distribution functions and quark masses, while also discussing its extension to quantum gravity via the Ricci flow.
This paper revisits two-body charmed anti-charmed baryonic decays by incorporating contributions alongside terms, demonstrating that these CKM-suppressed amplitudes are significantly enhanced in transitions and can substantially increase decay rates for specific channels like .
Using QCD two-point sum rules, this study quantitatively analyzes how the mass and decay constant of the meson in a hot and dense medium initially increase with temperature or baryon chemical potential before reaching a maximum and eventually vanishing at critical values that shift to lower thresholds as the opposing parameter increases.
Using the basis light-front quantization formalism, this study reveals that relativistic effects induce novel "W"-shaped structures in the leading-twist distribution amplitudes of -wave axial vector quarkonia, highlighting the necessity of relativistic frameworks for accurately modeling heavy quarkonium production and structure.
This paper investigates the time evolution of scalar condensate decay by numerically analyzing how parametric-resonance results converge to Feynman-diagrammatic decay rates across different instability bands and by comparing Bosonic and Fermionic Rabi models to attribute discrepancies at large times to Bose enhancement versus Pauli blocking.
This paper utilizes the operator product expansion within Pionless effective field theory to analyze high-momentum nucleon distributions in light nuclei, successfully extracting local-operator matrix elements from variational Monte Carlo data to accurately reconstruct single-nucleon distributions and establish approximate relations between single- and two-nucleon contributions in potentials lacking explicit non-nucleon degrees of freedom.
