Physics case  The overall picture of particle physics, the so-called Standard Model, has been recently probed by the discovery at CERN of the Higgs particle; it is consistent with the existence of three neutrinos. Oscillations between these neutrinos has been observed in many experiments  and are already a compelling evidence of new physics beyond the Standard Model.

Scientific goals :   Neutrinos are elementary particles produced abundantly in stars, in the Earth's atmosphere and in the cores of nuclear power plants. In 2006 CEA/IRFU and CNRS/IN2P3 have decided to officially launch the construction of the Double Chooz experiment. Two identical detectors are to be installed near the Chooz nuclear power plant, in the French Ardennes, at different distances from the reactors.
