A New Way to Look for Sterile Neutrinos

Abstract: There is an observed deficit of about -6% in the expected rate of anti-neutrino interactions when averaging over many different reactor experiments. While the significance of the deficit is low (98.6 % CL), there is speculation that a non-interacting “sterile” neutrino could be the cause. The possibility of a two-reactor/one-detector experiment at intermediate distances (100-500 meters) is investigated to look for a sterile neutrino in the mass range implied by this deficit. The potential sensitivity of an existing reactor experiment (Double Chooz) which has a single Near Detector at distances of 351 m and 465 m from two reactors of identical design is also investigated. Such a detector could investigate sterile neutrino in the ∆m2 range of 0.002 to 0.5 eV2 over 5 years of near detector running.
