First Results from the DoubleChooz Experiment

Building 6008 Conference Room

Neutrino oscillations have been experimentally confirmed for solar, atmospheric and reactor neutrinos. Previous experiments have determined parameters of neutrino mixing *12, *23, *m221, and *m231. One of the remaining parameters, *13, has only an upper limit of sin2(2*13) < 0.15 from the Chooz experiment. DoubleChooz is a new generation reactor neutrino experiment which is located near a two-core nuclear power plant in Northern France. DoubleChooz will use two identical detectors to reduce the systematic uncertainties related to the absolute knowledge of neutrino flux from nuclear reactors. One detector is located near the reactors to monitor the neutrino spectrum and one at a distance of ~1 km from the reactors to measure signal of disappearance of electron anti-neutrinos due to oscillations. The far detector has been running since April 2011 and construction of the lab for the near detector is underway. In this talk we will present preliminary data collected with the far detector and implication of our result for future neutrino experiments.
