For well over half a century, precision studies of neutron and nuclear β decays have been at
the forefront of searches for exotic electroweak physics. Recent advances in nuclear ab initio …

The Ultracold Neutron Asymmetry (UCNA) experiment was designed to measure the β-
decay asymmetry parameter, A 0, for free neutron decay. In the experiment, polarized …

This paper describes the mathematical basis for analysis of vertical time-of-flight (TOF)
measurements with ultracold neutrons (UCN). In contrast to conventional horizontal TOF …

The Nab Experiment aims to use the Spallation Neutron Source at Oak Ridge National Lab
to measure two parameters associated with the kinematics of the beta decay of free …

Ultracold neutrons (UCNs) are neutrons that have been cooled such that their kinetic energy
is on the order of their gravitational potential energy. Experimentally, ultracold neutrons are …

We study the combined sensitivity of measurements of electron-proton coincidence
asymmetries in polarized neutron beta-decay together with a measurement of the electron …
