First Full Dalitz Plot Measurement in Neutron -Decay using the Nab Spectrometer and Implications for New Physics
Francisco M. Gonzalez, Jin Ha Choi, Himal Acharya +89
Precision measurements of observables in neutron -decay are used to test the Standard Model description of the weak interaction and search for evidence of new physics. The Nab e…
The 3He(\vec n,p)3H parity-conserving asymmetry
M. Viviani, S. Baeßler, L. Barrón-Palos +28
Recently, the nHe collaboration reported a measurement of the parity-violating (PV) proton directional asymmetry $A_{\mathrm {PV}} = (1.55\pm 0.97~\mathrm {(st\ at)} \pm 0.24~\…
Precision pulse shape simulation for proton detection at the Nab experiment
Leendert Hayen, Jin Ha Choi, Dustin Combs +22
The Nab experiment at Oak Ridge National Laboratory, USA, aims to measure the beta-antineutrino angular correlation following neutron decay to an anticipated precision of appro…
Measurement of the Parity-Odd Angular Distribution of Gamma Rays From Polarized Neutron Capture on Cl
N. Fomin, R. Alarcon, L. Alonzi +61
We report a measurement of two energy-weighted gamma cascade angular distributions from polarized slow neutron capture on the Cl nucleus, one parity-odd correlation propor…

Using Nab to determine correlations in unpolarized neutron decay
L. J. Broussard, S. Baeßler, T. L. Bailey +28
The Nab experiment will measure the ratio of the weak axial-vector and vector coupling constants with precision and search for a Fierz term $b_…
The Nab Experiment: A Precision Measurement of Unpolarized Neutron Beta Decay
J. Fry, R. Alarcon, S. Baessler +69
Neutron beta decay is one of the most fundamental processes in nuclear physics and provides sensitive means to uncover the details of the weak interaction. Neutron beta decay can e…
