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.
This paper presents a novel, numerically and formally exact solution to the pion Bethe-Salpeter equation in the chiral limit, utilizing state-of-the-art QCD correlation functions while strictly satisfying axial Ward-Takahashi identities.
This paper presents a precise theoretical analysis of decays using the factorization-assisted topological-amplitude (FAT) approach, where 10 nonfactorizable parameters are globally fitted to 36 experimental data points to reveal that large strong phases in the amplitude cause destructive interference with the component, leading to a polarization hierarchy () that contradicts naive factorization predictions.
This paper initiates a program to investigate the ultraviolet completion of generalised Proca theories within the asymptotic safety paradigm, identifying non-perturbative fixed points that demonstrate the renormalisability of vector-tensor theories and constrain viable late-time cosmological scenarios.
This paper introduces a computationally efficient approximate energy-integration method that overcomes the limitations of previous schemes to accurately and robustly identify collisional neutrino flavor instabilities across diverse regimes in high-energy astrophysical simulations like core-collapse supernovae and binary neutron star mergers.
This paper demonstrates that spontaneous symmetry breaking can persist up to arbitrarily high temperatures in four-dimensional ultraviolet-complete quantum field theories by identifying explicit finite- benchmark models where a negative thermal mass prevents symmetry restoration despite asymptotic freedom.
