摘要：I present recently developed effective field theory frameworks for computing radiative corrections to low-energy electroweak processes. Utilizing this approach, I provide the most precise and accurate predictions with uncertainties for several key observables: cross sections for elastic (anti)neutrino-electron, (anti)neutrino-nucleon, and coherent elastic (anti)neutrino-nucleus scattering; as well as rates and energy spectra in neutron, pion, kaon, and muon decays. New results serve as inputs for accurately normalizing (anti)neutrino fluxes in cross-section and oscillation experiments, extracting quark and lepton mixing matrices, refining models of solar and reactor neutrino physics, determining the nucleon axial-vector structure, and searching for new physics in low-energy electroweak interactions.
