Research Abstract

We built a neutrino detector at Chooz nuclear power plant in France and identified the third neutrino oscillation by reactor neutrinos (Double Chooz experiment). We measured neutrino mixing angle θ_<13> with various analysis methods. These results have determined all the neutrino mixing angles and opened a window to measure the leptonic CP violation and to determine the neutrino mass hierarchy, that lead a new development of neutrino physics. We also measured mass squared difference Δm^2_<31> by making use of the baseline dependence of the reactor neutrino oscillation for the first time.
