New Limits on $n \to n^{'}$ Transformation from HFIR Cold Neutron Beam

James M. Rogers, Leah J. Broussard, Christopher B. Crawford +16

Hypothetical neutron $n$ to sterile neutron $n^{'}$ transformations would violate baryon number $B$ and point to the nature of Dark Matter. We performed a new search for $n…

First Full Dalitz Plot Measurement in Neutron $I^^{2}$ -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 $I^^{2}$ -decay are used to test the Standard Model description of the weak interaction and search for evidence of new physics. The Nab…

Optimization of Ray-tracing Simulations to Confirm Performance of the GP-SANS Instrument at the High-Flux Isotope Reactor

James M. Rogers, Matthew J. Frost, Lisa DeBeer-Schmitt

The CG-2 beamline at the High Flux Isotope Reactor (HFIR) exhibits a notable discrepancy between observed count rates and the count rates we would expect based on a Monte-Carlo neu…
