Title: Studying Neutrino Directionality with the Double Chooz Experiment

Doctoral Candidate: Erica Caden

Abstract: Double Chooz is a two detector reactor neutrino oscillation experiment, searching for the neutrino mixing angle theta-13. We detect neutrinos using the two part interaction of Inverse Beta Decay. The spatial separation of the events in this interaction also lets us measure the direction and opening cone that locates the neutrino source. Neutrino Directionality is a useful tool with applications in studying supernovae as well as nuclear reactors. We identify the neutrino source at phi=84.5 +/- 1.35 degrees, and the cone which contains 68% of the neutrino signal is calculated to have a half-aperture opening of 9.4 degrees. Our improvement over previous results comes from greater statistics and an improved position reconstruction algorithm.
