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 develops a new resonating group method formalism for baryon-baryon interactions that accounts for unequal oscillator frequencies arising from distinct quantum numbers, and applies this consistent framework to the system within a chiral SU(3) quark model to demonstrate its advantages over traditional approaches.
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.
This paper proposes and rigorously computes a novel mechanism for generating microscopic gravitational waves during cosmological first-order phase transitions, driven by the braking of heavy particles traversing expanding bubble walls, which offers a unique observational signature correlated with particle mass and wall velocity for probing new physics.
This paper demonstrates that resonant pair-production terms in a lattice gauge theory enable the formation of stable, high-energy "repulsively bound" hadrons through a novel dynamical mechanism, a finding supported by matrix product state simulations and an effective model that suggests experimental realization on modern quantum hardware.
This paper proposes an improved method for determining entanglement entropy in Deep Inelastic Scattering (DIS) using proton structure functions and parton distribution functions, demonstrating that the results align closely with H1 experimental data across various kinematic ranges.
