Abstract
Double Chooz is a reactor neutrino experiment that aims at a precise measurement of the neutrino mixing angle θ13. This experiment has been detecting electron antineutrinos using a single detector, that is located ∼ 1.050m away from two reactor cores at the Chooz nuclear power station in France. This article gives a review of the θ13 analysis results with neutrons originated from inverse β-decay captured on gadolinium, as well as recently-reported first measurement with those on hydrogen. These results are, respectively, sin2 2θ13 = 0.109±0.030(stat.)±0.025(syst.) and sin2 2θ13 = 0.097 ± 0.034(stat.) ± 0.034(syst.) obtained as best fit values to the neutrino rate and the energy spectrum. The two independent approaches demonstrate the consistency of results for θ13 in datasets that are statistically different and also some distinct in systematic uncertainties. Physics studies other than the θ13 measurement have been performed to make a direct background detection during two reactors off period, and a first test of Lorentz violation using reactor neutrinos.
