Progress on the St. Benedict at the NSL

ORAL

Abstract

Nuclear beta decays provide a unique avenue for testing the electroweak part of the Standard Model through precision measurements. Physics beyond the Standard Model would manifest itself in these transitions through a variety of possible effects, including a non-unitarity of the Cabibbo-Kobayashi-Maskawa quark mixing matrix, scalar or tensor currents, and interactions involving right-handed neutrinos. These various effects can be probed for via measurements of the beta-neutrino angular correlation parameter in superallowed mixed beta decay transitions. To that end, the Superallowed Transition Beta-Neutrino Decay Ion Coincidence Trap (St. Benedict) is currently under construction at the University of Notre Dame Nuclear Science Laboratory. The status of St. Benedict will be presented.
