This work assesses the sensitivity of the upcoming gamma-ray missions COSI and AMEGO-X to sub-GeV fermionic dark matter in vector-scalar portal models and demonstrates that COSI can provide leading constraints on gamma-ray lines beyond CMB limits, while AMEGO-X can probe most of the viable parameter space for continuous gamma rays.
The work constructs a stable solution of a type-3 electric flux tube in SU(3) gauge theory with fundamental scalar fields that resists Schwinger pair production, while noting the failure to construct a corresponding type-8 solution.
This paper investigates the Standard Model predictions for decays into charmed mesons and leptons by employing perturbative QCD form factors constrained by lattice QCD inputs and heavy quark spin symmetry to calculate branching fractions, lepton flavor violating observables, and detailed angular distributions.
This paper demonstrates through time-domain simulations that the nonlinear scalar ergoregion instability on horizonless spinning ultracompact spacetimes saturates via a weakly turbulent direct cascade, which rapidly transfers energy to small scales and populates the stable light ring with higher-order modes, suggesting similar turbulent mechanisms will shape gravitational wave signatures in fully gravitational scenarios.
This paper investigates the dependence of initial-state radiation corrections in -annihilation processes on the factorization scale by analyzing various prescriptions within leading and next-to-leading logarithmic approximations and optimizing the scale choice through comparison with complete two-loop results.
This paper revisits charged lepton flavor violation in the minimal type-I seesaw model using updated data, revealing that certain semileptonic tau decays can dominate over purely leptonic channels in specific parameter regions while heavy-meson decays remain experimentally inaccessible.
This paper employs QCD sum rules to construct interpolating currents for gluonic hidden-charm tetraquark states with quantum numbers, predicting the existence of six stable states and estimating their hidden-bottom partners, decay channels, and production mechanisms to guide future experimental searches.
This study utilizes astrophysical observations, including massive pulsar measurements, NICER data, and GW170817 tidal deformability constraints alongside perturbative QCD calculations, to significantly restrict the admissible parameter space for the equation of state of cold, dense strongly interacting matter.
This paper investigates the hadronic molecule using QCD sum rules, predicting its mass to be MeV and its total width to be MeV, which indicates that the state decays strongly into ordinary mesons via dominant fall-apart and subdominant annihilation mechanisms.
This paper establishes a systematic effective field theory framework using chiral symmetry to connect ultraviolet interactions to low-energy hadronic observables, demonstrating that while baryon-antibaryon oscillations probe a limited subset of operators, dinucleon decay offers a broader sensitivity to previously unexplored channels and parameter space.
