Limits on the Existence of sub-MeV Sterile Neutrinos from the Decay of Be in Superconducting Quantum Sensors

S. Friedrich, G. B. Kim, C. Bray +14

Sterile neutrinos are natural extensions to the standard model of particle physics and provide a possible portal to the dark sector. We report a new search for the existence of sub…
