Description

The existing 4 sigma discrepancy between the neutron lifetime measurements in bottle versus beam experiments has been interpreted as a sign of neutrons decaying to dark particles with a 1% branching fraction. I will present a brief summary of this proposal, including particle physics models accommodating this scenario, as well as discuss related theoretical and experimental follow-ups. I will then elaborate on the prospects for verifying the neutron dark decay hypothesis in current and upcoming nuclear physics experiments.
