Abstract

Precision measurements in free neutron beta decay serve to determine the coupling constants of beta decay and offer several stringent tests of the standard model. This paper describes the free neutron beta decay program planned for the Fundamental Physics Beamline at the Spallation Neutron Source at Oak Ridge National Laboratory, and puts it into the context of other recent and planned measurements of neutron beta decay observables.
