This paper investigates how introducing a new X17 vector boson could resolve existing Standard Model tensions and act as a portal to the dark sector, thereby motivating further experimental and theoretical research into physics beyond the Standard Model.
This paper demonstrates that spectral splits in dense neutrino gases arise from a structured redistribution of quantum resources—specifically the maximization of entanglement entropy and minimization of non-local magic—thereby establishing a direct link between computational complexity metrics and astrophysical flavor evolution.
This paper investigates the infrared behavior of photon yields in nonlinear Compton scattering, deriving analytical expressions for both idealized plane-wave fields—where it resolves the logarithmic divergence in unipolar cases via formation length arguments—and realistic tightly-focused laser beams, where it quantifies the leading-order quantum corrections to the classical angular distribution.
This paper utilizes QCD light-cone sum rules to calculate transition form factors and predict the branching fractions for the semileptonic decays and , with the latter's result validating the method against experimental data to provide theoretical guidance for future measurements of the former.
This paper presents a comprehensive SMEFT analysis of correlated and rare semileptonic transitions, demonstrating that while complex left-handed four-fermion operators and electroweak corrections explain anomalies, flavor-universal couplings are ruled out by kaon data, necessitating Minimal Flavor Violation frameworks like or to reconcile predictions with experimental bounds while predicting observable CP asymmetries.
This paper presents a phenomenological study of charged long-lived staus predicted by the gauge-mediated supersymmetry breaking model, demonstrating their potential for discovery via kinked tracks and displaced vertices at the Future Circular Collider (FCC-ee) for lifetimes ranging from 20 cm to 20 m.
This paper proposes a novel inverse problem framework for calculating non-perturbative QCD quantities by deriving them from high-energy perturbative inputs, utilizing Tikhonov regularization to stabilize the inherently ill-posed problem and demonstrating its efficacy through toy models.
Using leading-order Faddeev techniques in the zero-coupling limit, this study demonstrates that the system exhibits universal Efimovian halo-bound characteristics, where ground state properties are rendered regulator-independent through the inclusion of a three-body force.
This paper presents a comprehensive phenomenological study of radiative electroweak symmetry breaking, demonstrating how its characteristic logarithmic potential leads to a light scalar boson and first-order phase transitions, thereby enabling the exploration of conformal symmetry breaking scales up to GeV through combined future collider and gravitational wave observations.
This paper proposes that regular primordial black holes can evaporate completely without forming exotic remnants by redefining their regularization parameters, thereby providing a unified framework to resolve both the black hole singularity problem and the dark matter abundance through modified Hawking evaporation dynamics.
