The status of tests of the standard electroweak model and of searches for new physics in
allowed nuclear β decay and neutron decay is reviewed including both theoretical and …

Experiments with cold and ultracold neutrons have reached a level of precision such that
problems far beyond the scale of the present standard model of particle physics become …

We study radiative corrections to low-energy charged-current processes involving nucleons,
such as neutron beta decay and (anti) neutrino-nucleon scattering within a top-down …

Scalar and tensor interactions were once competitors to the now well-established VA
structure of the standard model weak interactions. We revisit these interactions and survey …

We compute the electromagnetic corrections to neutron β decay using a low-energy
hadronic effective field theory. We identify new radiative corrections arising from virtual pions …

We consider the role of precision measurements of beta decays and light meson semi-
leptonic decays in probing physics beyond the Standard Model in the LHC era. We describe …

A complete and critical survey is presented of all half-life, decay-energy, and branching-ratio
measurements related to 20 superallowed 0+→ 0+ decays; no measurements are ignored …

The accuracy of V ud determinations from superallowed β decays critically hinges on control
over radiative corrections. Recently, substantial progress has been made on the single …

Determinations of| V ud| and| V us| along with their implications for the unitarity test| V ud| 2+|
V us| 2+| V ub| 2= 1 are discussed. The leading two-loop radiative corrections to neutron β …

A bstract We present the first and complete dispersion relation analysis of the inner radiative
corrections to the axial coupling constant g A in the neutron β-decay. Using experimental …
