Bartosz Fornal, University of Utah, will be speaking.
The presentation title is "Neutron's Dark Secret."
The neutron is one of the most important constituents of matter. It is absolutely crucial for the existence of atoms heavier than hydrogen. Surprisingly, the precise value of the free neutron lifetime is still an open question, with two types of experiments (bottle and beam measurements) providing substantially different answers. I will describe the recently proposed interpretation of this discrepancy as a sign of neutron decaying to dark particles, and show that phenomenologically consistent models of this type can be constructed. I will also elaborate on the theoretical developments around this idea and discuss the efforts undertaken to verify it experimentally. more information...
