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…
Backscattering Study of Electrons from 0.1 to 3.4 MeV
M. Kanafani, X. Fléchard, O. Naviliat-Cuncic +10
Benchmarking simulation codes for electron transport and scattering in matter is a crucial step for estimating uncertainties in many applications. However, experimental data for el…
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…
Performance of the MORA Apparatus for Testing Time-Reversal Invariance in Nuclear Beta Decay
N. Goyal, A. Singh, S. Daumas-Tschopp +40
The MORA experimental setup is designed to measure the triple-correlation D parameter in nuclear beta decay. The D coefficient is sensitive to possible violations of time-reversal…
High-Precision Excited-State Nuclear Recoil Spectroscopy with Superconducting Sensors
C. Bray, S. Fretwell, L. A. Zepeda-Ruiz +30
Superconducting sensors doped with rare isotopes have recently demonstrated powerful sensing performance for sub-keV radiation from nuclear decay. Here, we report the first high-re…
