This paper proposes that five-dimensional 't Hooft-Polyakov monopole strings, which restore non-abelian gauge symmetry in their cores, function as axion strings for extra-dimensional axions, thereby enabling a viable post-inflationary cosmology for high-quality axion dark matter by parametrically separating string tension from the quantum gravity scale.
This paper proposes a minimal dark gauge framework that naturally generates small neutrino masses via an inverse seesaw mechanism with a dynamically suppressed lepton-number violating parameter while simultaneously stabilizing a dark matter candidate consistent with current experimental constraints.
This paper presents recent LHCb results showing that the significantly enhanced production ratios of heavy flavor hadrons (such as and ) in high-multiplicity collisions suggest a modification of the hadronization mechanisms in these events.
This paper computes diffractive structure functions using JIMWLK evolution constrained by HERA vector meson data, comparing results to existing measurements and providing predictions for nuclear modification factors and diffractive-to-total cross-section ratios at the future Electron-Ion Collider (EIC).
This paper extends Chiral Perturbation Theory for QCD-like theories with two non-degenerate fermion flavors to next-to-next-to-leading order, deriving reduced Lagrangians and calculating corrections to key observables to fit lattice data for the $Sp(4)$ gauge theory, thereby demonstrating the critical role of higher-order terms in understanding strongly interacting pionic dark matter.
This paper demonstrates the direct computation of hadronic tensors in (1+1)-dimensional U(1) and SU(2) gauge theories using quantum algorithms on classical hardware, successfully extracting reliable hadron form factors that align with exact diagonalization results.
This paper employs SU(3) flavor symmetry and final-state interaction theory to predict that meson decays can produce scalar and molecular states with branching ratios up to and significant $CP$ asymmetries, while suggesting that the observed state is likely a molecule.
This paper presents the conceptual design and performance evaluation of the LHC, a feasible HL-LHC-based antimuon-proton collider utilizing ultra-cold beam technology to achieve 5.3 TeV center-of-mass energy and high luminosity for exploring QCD, Higgs physics, and beyond-Standard-Model phenomena.
This paper proposes a unified framework based on and cyclic symmetries that describes type-I Dirac seesaw models using three universal parameters, revealing Hermitian textures in down-type quark and light neutrino mass matrices while exploring their phenomenological implications and renormalization group stability.
This paper introduces a partial-wave basis for five-point tree amplitudes of identical scalars to derive splitting constraints that, at low mass levels, uniquely determine five-point data from four-point coefficients and manifest hidden zeros, while revealing that higher-spin exchanges necessitate additional input for complete rigidity.
