Description
In 2011, a re-evaluation of the anti-neutrino spectrum emitted by nuclear reactors revealed a 6% deficit between the observed flux and the expected one. This anomaly is significant at 2.7sigmas and can be explain by a new oscillation at short range due to a light sterile neutrino, with parameter Δm² = 0.1-1 eV. The STEREO detector in construction at ILL will be the first ever to measure with precision the anti neutrino spectrum and flux at very short distance (9-11m) from the source of emitted neutrinos and it will be able to confirm or reject the existence of this light sterile neutrino. In this presentation I will introduce the relevant parameter to study the neutrino oscillation, the STEREO detector and its discovery potential.
