Abstract
We report the latest results on θ13 measurement from the Double Chooz experiment based on 33.71 GW-ton-years exposure (reactor power × target mass × live-time) to electron antineutrinos from the CHOOZ reactor power plant in France. The Double Chooz detector is located at a distance of 1050 m where deficit of electron antineutrinos is expected with non-zero θ13 neutrino mixing angle. We observed 8,249 antineutrino candidates while 8,937 events are expected in case of θ13=0. The deficit is interpreted as an evidence for electron antineutrino disappearance. From a fit to the observed energy spectrum, we obtained .
