Reactor Neutrino Oscillation Measurement with Double Chooz Hydrogen Data — •Philipp Kampmann, Ilja Bekman, Denise Hellwig, Stefan Schoppmann, Michael Soiron, Achim Stahl, and Christopher Wiebusch — III. Physikalisches Institut B - RWTH Aachen

The Double Chooz experiment is a reactor neutrino experiment with the purpose of a precise measurement of the neutrino mixing angle θ₁₃ . The setup consists of two identical liquid scintillator detectors at an average baseline of 400m and 1km to two nuclear reactor cores in Chooz, France. The neutrinos are detected by the signature of the inverse beta decay, which consists of a positron signal and a delayed neutron capture signal. From the positron measurement the neutrino energy is extracted. Neutrons are captured either by gadolinium or hydrogen in the scintillator. Due to different capture energies, two independent data samples are obtained. This presentation describes the determination of the neutrino mixing angle θ₁₃ using a likelihood fit approach of hydrogen capture data.
