New Limits on Transformation from HFIR Cold Neutron Beam
James M. Rogers, Leah J. Broussard, Christopher B. Crawford +16
Hypothetical neutron to sterile neutron transformations would violate baryon number and point to the nature of Dark Matter. We performed a new search for $n…
Characterization of Low-energy Ionization Signals in Silicon Detectors for the Nab Experiment
R. J. Taylor, August Mendelsohn, Arlee Shelby +22
The Nab (Neutron a b) experiment is designed to measure the beta-antineutrino angular correlation in free neutron decay with an ultimate precision goal of 0.1%, providing input…
A gaseous-helium cooling system for silicon detectors in the Nab experiment
Love Richburg, Noah Birge, Nadia Fomin +40
The Nab experiment aims to extract the neutron beta decay correlation coefficients 'a' and 'b'. This will be accomplished using a 7 m tall electromagnetic spectrometer which measur…
From Commissioning to Precision Data-Taking: Resolving Operational Challenges in the Nab Detector Systems
L. J. Broussard, H. Acharya, R. Alarcon +36
Our understanding of the weak mixing of quarks, described by the Cabibbo Kobayashi Maskawa (CKM) matrix, currently presents an anomaly. Thanks to major strides in both theory and e…
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…
