Dark neutrons underground

02/10/2022 - 2:00pm to 3:00pm
Speaker(s) / Presenter(s): 
Matheus Hostert (Perimeter Institute & U. Minnesota)
Type of Event (for grouping events):
I will discuss signatures of dark baryons that mix with the neutron at underground neutrino experiments. Intense neutron sources can produce dark neutrons that upon transversing the shielding designed to stop normal neutrons, can be absorbed in neutrino detectors. We point out that the IsoDAR experiment, a proposal to place a high-intensity cyclotron at Yemilab, can place the strongest constraints in parameter space by searching for this neutron-shinning-through-walls signature. We also discuss the nuclear absorption of dark neutrons at large volume neutrino detectors when they constitute dark matter.
