Abstract

The Double Chooz experiment presents improved measurements of the neutrino mixing angle Ɵ13 using the data collected in 467.90 live days from a detector positioned at an average distance of 1050m from two reactor cores at the Chooz nuclear power plant. Several novel techniques have been developed to achieve significant reductions of the backgrounds and systematic uncertainties with respect to previous publications, whereas the efficiency of the (Formula Presented.) signal has increased. The value of Ɵ13 is measured to be sin²2Ɵ₁₃ = 0.090_-0.029^+0.032 from a fit to the observed energy spectrum. Deviations from the reactor (Formula Presented.) prediction observed above a prompt signal energy of 4MeV and possible explanations are also reported. A consistent value of Ɵ₁₃ is obtained from a fit to the observed rate as a function of the reactor power independently of the spectrum shape and background estimation, demonstrating the robustness of the Ɵ₁₃ measurement despite the observed distortion.
