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 …

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 …

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 …

A bstract We discuss low-energy and collider constraints on the effective couplings
characterizing non-standard charged current interactions. A direct comparison of low-energy …

Precision measurements in nuclear β decay offer a sensitive window to search for new
physics beyond the standard electroweak model. Searches for new physics are also a …

The role of β decay as a low-energy probe of physics beyond the standard model is
reviewed. Traditional searches for deviations from the standard model structure of the weak …

We present an apparatus for detection of cyclotron radiation yielding a frequency-based
β±kinetic energy determination in the 5 keV to 2.1 MeV range, characteristic of nuclear β …

Background: The β decays of 3 H and 6 He can play an important role in testing nuclear
wave-function calculations and fixing low-energy constants in effective-field theory …

A bstract Tritium beta-decay is the most promising approach to measure the absolute
masses of active light neutrinos in the laboratory and in a model-independent fashion. The …

The beta decay process offers unique possibilities to search for so-called exotic, non-
standard model components in the weak interaction, and for testing its fundamental …
