The Nab spectrometer at Oak Ridge National Lab, and Free Neutron Beta Decay

Nab, an experiment that allows studying unpolarized neutron beta decay at the Spallation Neutron Source at Oak Ridge National Lab, aims to determine a, the neutrino-electron correlation coefficient, and b, the Fierz interference term, with high precision. Such measurements provide opportunities to search for evidence of extensions to the Standard Model. In the past year, installation of the spectrometer has started in earnest at the Spallation Neutron Source. I will discuss the experiments motivation and design, and report on installation progress.
