This paper presents the first relativistic next-to-leading order Chiral Perturbation Theory calculation of non-leptonic hyperon decays, explicitly incorporating loop corrections and resonance saturation for low-energy constants to achieve a successful fit of both - and -wave amplitudes while highlighting the crucial role of resonances.
This paper demonstrates that baryogenesis via sphalerogenesis can be successfully realized in Standard Model extensions featuring new multiplet fields (such as fermionic quintuplets and septuplets) with TeV-scale masses and CP-violating Yukawa interactions, yielding a phenomenologically viable and testable scenario consistent with current electron electric dipole moment limits and future collider searches.
This paper investigates charged current induced electron-proton scattering at JLab and MAMI by calculating various cross sections and polarization observables with and without time-reversal invariance, aiming to provide alternative constraints on the axial vector form factor to benefit neutrino oscillation experiments.
This paper presents a sensitivity study using the BESIII experiment to propose a model-independent method for determining the branching fraction of decays into three-body final states by simultaneously analyzing four specific semileptonic -meson decay channels.
This paper demonstrates that combining next-to-next-to-leading-order Standard Model predictions with approximate next-to-next-to-leading-order SMEFT interference corrections for top-antitop pair production at 13 and 13.6 TeV yields robust, high-precision constraints on the top chromomagnetic operator , probing effective scales up to 3.9 TeV.
This paper demonstrates that incorporating full renormalization-group running effects, particularly through Yukawa mixings, enables stringent constraints on all 297 dimension-7 baryon-number-violating SMEFT Wilson coefficients from nucleon decay data, significantly extending the reach beyond the first and second fermion generations compared to tree-level analyses.
Using the Bethe-Salpeter formalism within the impulse approximation, this paper computes the isospin-breaking baryonic form factors for pions and kaons, yielding a baryonic radius of 0.043(2) fm for the pion that aligns with dispersive benchmarks and predicting larger radii of approximately 0.26 fm for kaons that are compatible with chiral QCD models.
This paper presents calculations of space-like electromagnetic form factors and charge radii for both light and heavy-light pseudoscalar mesons using a flavor-dependent Bethe-Salpeter framework.
This paper investigates how uncertainties in model predictions for the muon content of extensive air showers relate to specific hadron-air interaction properties, utilizing the new QGSb Monte Carlo generator to analyze interaction mechanisms and their constraints from accelerator data.
This paper demonstrates that introducing a massive gauge boson with family-dependent couplings to left-handed leptons allows quantum effects to increase the rank of the neutrino mass matrix at the one-loop level, thereby enabling the dynamical generation of observed neutrino mass differences and mixing angles.
