TLDR
The Double Chooz experiment has observed 8,249 candidate electron antineutrino events in 227.93 live days with 33.71 GW-ton-years (reactor power x detector mass x livetime) exposure using a 10.3 cubic meter fiducial volume detector located at 1050 m from the reactor cores of the Choock nuclear power plant in France as discussed by the authors.
Abstract
The Double Chooz experiment has observed 8,249 candidate electron antineutrino events in 227.93 live days with 33.71 GW-ton-years (reactor power x detector mass x livetime) exposure using a 10.3 cubic meter fiducial volume detector located at 1050 m from the reactor cores of the Chooz nuclear power plant in France. The expectation in case of theta13 = 0 is 8,937 events. The deficit is interpreted as evidence of electron antineutrino disappearance. From a rate plus spectral shape analysis we find sin^2 2{\theta}13 = 0.109 \pm 0.030(stat) \pm 0.025(syst). The data exclude the no-oscillation hypothesis at 99.9% CL (3.1{\sigma}).

Prediction of the Reactor Antineutrino Flux for the Double Chooz Experiment

TL;DR: In this paper, the authors compared the deterministic lattice code, DRAGON, against data, and then applied this code to make a prediction for the antineutrino flux from the Chooz BI and B2 reactors.

Monte Carlo aided design of the inner muon veto detectors for the Double Chooz experiment

TL;DR: In this article, the inner muon veto was designed to suppress correlated background induced by cosmic muons in the detectors, which achieved an efficiency of 99.978 +- 0.004% for rejecting muon events and an efficiency between 98.98% and 99.
