This paper investigates the dark axion portal model by analyzing missing energy signatures in electron fixed-target experiments like NA64e and LDMX, deriving new constraints on dark photon and ALP production mechanisms, and establishing limits on CP-violating couplings using current fermion electric dipole moment measurements.
This paper presents the first complete next-to-next-to-next-to-leading order QCD calculation of heavy-to-light semi-leptonic decay structure functions, enabling precision predictions for triple differential rates that are crucial for determining CKM matrix elements and resolving tensions in measurements.
This paper derives and analyzes higher-order correction terms up to for the invariant mass expressions of multi-particle systems in collider physics, demonstrating that the standard zeroth-order approximations are remarkably robust due to significant cancellations in the correction coefficients.
Using leading-order chiral perturbation theory, this paper maps the low-energy QCD phase diagram under magnetic fields with baryon and isospin chemical potentials, identifying various exotic phases including a chiral soliton lattice and a hybrid vortex phase that may be relevant to neutron stars at magnetic fields around G.
This paper presents the first complete perturbative QCD corrections to heavy-to-light structure functions using a hybrid computational strategy, providing state-of-the-art predictions for semi-leptonic -meson decays and revealing novel boundary-effect terms essential for consistent mass-scheme reformulations at third order.
This paper reviews recent theoretical and experimental progress in the decays of and hadrons, focusing on calculations addressing neutral current anomalies, resolving the exclusive-inclusive discrepancy in CKM element determinations, and assessing the status of lepton universality ratios.
This paper challenges the prevailing linear paradigm of black hole relaxation by revealing a new nonlinear regime where a "saddle-node ghost" traps excited remnants, creating a universal power-law delay that manifests as a distinctive quiescence-burst signature in gravitational waves.
This paper demonstrates that a low-temperature reheating scenario in the minimal Universal Extra Dimension framework can dilute the Kaluza-Klein dark matter relic abundance through entropy injection, thereby reviving previously excluded parameter regions that remain consistent with current observational and collider constraints.
This paper proposes a new class of primordial non-Gaussianity arising from direct inflaton couplings that exhibit hybrid light-heavy field characteristics, leading to oscillatory modulations in the galaxy power spectrum which are analyzed using BOSS DR12 data to establish the first constraints on this extended parameter space while demonstrating enhanced sensitivity for future surveys.
This paper systematically investigates spin-one dark matter-nucleus scattering within effective field theories by deriving nonrelativistic operators, matching them to relativistic descriptions, and using direct detection data to constrain interaction coefficients across a wide mass range while proposing a UV-complete model for complex spin-one dark matter.
