Investigations of the Sensitivity of the Double Chooz Experiment to sterile Neutrinos in a 3+2 Scenario — Denise Hellwig, Philipp Soldin, •Yannic Sommer, Achim Stahl, and Christopher Wiebusch — III. Physikalisches Institut B, RWTH Aachen University

The Double Chooz experiment is a reactor neutrino disappearance experiment for the precise measurement of the neutrino mixing angle θ₁₃. Two identical liquid scintillator detectors with baselines of 1050 m and 400 m are installed at the nuclear power plant in Chooz, France. These are measuring the flux of antineutrinos from two reactor cores utilizing the signature of the inverse beta decay (IBD). To explain the deviation from the measured data to the theoretically predicted neutrino flux, one possibility would be non weakly-interacting sterile neutrinos. A study of the sensitivity to a scenarion with two additional sterile neutrinos will be presented.
