Description

The experimental & theoretical research on physics of massive neutrinos is based on standard paradigm of three-neutrino mixing, which describes the oscillations of neutrino flavors measured in solar, atmospheric a& long-baseline experiments. However, several anomalies , corresponding to an L/E of 1m/MeV could be interpreted by involving sterile neutrino as RAA & Galium anomaly.
STEREO was designed to investigate this conjecture, which would potentially extend the SM, detector provides a complete study of anomalies for a pure 235U antineutrino spectrum, using HEU core
We will describe an analysis of full set of data generated by STEREO & an accurate prediction of reactor. The measured antineutrino energy spectrum suggests that anomalies originate from biases in nuclear experimental data used forpredictions, while rejecting the hypothesis of a light sterile neutrino. Our result supports neutrino content of SM & establishes a new reference for 235U antineutrino energy spectrum.
