Abstract
Conversions between neutrons π and dark matter candidate sterile neutrons πβ² have been proposed as a mechanism for baryon number β¬ violation. In the case that there is a small mass difference Ξβ’π between the π and the πβ² states, oscillations can be induced by compensating for Ξβ’π with a magnetic field. A search for such neutron oscillations was performed at the Spallation Neutron Source by looking for anomalous neutron transmission through a strongly absorbing cadmium wafer inside of a 6.6 T magnet. The approach described here saw no regenerated neutrons above background, which provides an improved limit for neutronβsterile neutron transformations for a range of Ξβ’π between 0.1 and 1000 neV.
