Results of STEREO and PROSPECT, and status of sterile neutrino searches

Reactor neutrinos have been an intense field of investigation for the last decade. Two anomalies are discussed in this document. First, a status of the sterile neutrino searches by STEREO, PROSPECT and DANSS is presented. The best-fit parameters of active-to-sterile oscillations from the Reactor Antineutrino Anomaly are strongly rejected by these experiments. Second, the analyses of the shape anomaly (“5 MeV bump”) by STEREO and PROSPECT, both using a virtually pure-${}^{235}$U neutrino flux, are detailed. Results show a significant excess of events at 5-6 MeV and indicate that the bump observed at commercial reactors is not specific to a particular isotope but rather shared among U and Pu.
