The paper proposes DREAMuS, a fixed-target experiment at HIAF designed to search for GeV-scale muon-philic dark matter mediated by light flavor-violating bosons, demonstrating competitive sensitivity to couplings around and highlighting the enhanced discovery potential of a complementary beam option for sub-200 MeV dark matter.
This paper compares the pion decay width in a uniform magnetic field calculated via chiral perturbation theory with lattice QCD results, finding consistency at large magnetic fields while attributing discrepancies at weak fields to differences in pion decay constants.
This paper introduces and validates a novel no-reaction-plane method for extracting directed and elliptic flows in heavy-ion collisions using simple count asymmetries, demonstrating through PHSD model simulations that it accurately captures flow fluctuations without the need for event-plane reconstruction.
This paper utilizes QCD sum rule methods to model the resonance as a all-charm tetraquark in a diquark-antidiquark configuration, calculating its mass and decay widths to demonstrate consistency with experimental data and support its interpretation as a tensor state.
This paper investigates the lifetimes and inclusive semileptonic decay widths of doubly heavy baryons using the heavy quark expansion with next-to-leading-order corrections and bag model matrix elements, predicting specific lifetime hierarchies and highlighting the crucial role of -exchange contributions in explaining the large lifetime splitting observed in the doubly charmed sector.
This study demonstrates that neutron star observables in hybrid equation-of-state models retain significant sensitivity to the choice of low-density nuclear matter models at commonly adopted transition densities (), implying that lowering the transition density is necessary to minimize systematic uncertainties and achieve model-independent predictions.
This paper extends perturbative Gubser flow solutions to derive analytic nonlinear response relations for flow harmonics and , revealing that a mismatch between participant and reaction planes introduces a critical angular factor that can significantly alter the magnitude and even the sign of effective nonlinear response coefficients.
This paper reviews constraints on baryon inhomogeneities derived from deuterium abundance measurements, concluding that while current and future data leave electroweak baryogenesis largely unconstrained, they significantly limit the viability of various alternative baryogenesis scenarios.
Using 15 years of Fermi-LAT data and new eROSITA constraints, this study revises the GeV gamma-ray emission of the Vela Jr supernova remnant as primarily shell-like with minimal pulsar wind nebula contribution, and finds that a hybrid lepton-hadron model best explains the multi-wavelength spectrum, suggesting a hadronic origin for the GeV emission while the TeV emission remains predominantly leptonic.
This paper proposes a minimal radiative Dirac neutrino mass model stabilized by a non-invertible fusion rule from a gauging, which successfully generates one-loop neutrino masses, provides a viable bosonic dark matter candidate, and remains consistent with current lepton flavor violation and magnetic moment constraints.
