Analysis of the aCORN NG-6 Dataset
ORAL
Abstract
The aCORN experiment is designed to measure the angular correlation ``$a$'' between electron and neutrino momenta in free neutron decay. Measurement of the $a$ correlation constrains the Standard Model weak interaction coupling constants ratio $g_A/g_V$, in a complementary manner to the current best constraints which come from the ``$A$'' polarized neutron beta decay asymmetry. Along with pinning down Standard Model parameters, comparison between high-precision measurements of multiple neutron decay observables probes Beyond-Standard-Model interactions. aCORN collected data over the previous two years on the NG-6 cold neutron beamline at the NIST Center for Neutron Research. aCORN has since re-located to the new, higher-flux NG-C beamline. This talk describes the present status of analysis of the aCORN NG-6 dataset, outlining the main systematics and corrections for the measurement.
