Double Chooz is an electron antineutrino disappearance experiment observing neutrinos originating from the Chooz nuclear power plant and interacting in our detector. The flux of electron anti-neutrinos is altered through neutrino oscillations and thereby allows to measure Θ13. The Double Chooz Collaboration published first results on its search for the neutrino mixing angle Θ13 in 2011. The current analysis comprises about 100 days of data taken since April 2011. Performing a so-called rate+shape analysis, a best-fit value for sin2 2Θ13 = 0.086 is reported with uncertainties of ±0.041 (stat) ±0.030 (syst) using Δm2 13 = 2.4 · 10−3 eV2. This article provides details about the analysis that lead to this result.
