Evidence against sterile neutrinos from the Daya Bay Experiment
Prevailing models of antineutrino emission by nuclear reactors do not
agree with observations. This discrepancy has been considered
possible evidence for neutrino oscillation to non-interacting, or
sterile, neutrino states. Although the existence of sterile neutrinos
would have profound implications, a variety of measurements by the
Daya Bay Experiment disfavor sterile models. I will summarize these
observations with a particular focus on the latest result: a precise
measurement of the antineutrino flux versus reactor fuel burn-up.
I’ll wrap up with a provocative question: does any compelling evidence
for sterile neutrinos remain?
