VIRTUAL INPA SEMINAR – Stefan Schoppmann (UC Berkeley)
September 18, 2020 @ 12:00 pm - 1:00 pm
Speaker: Stefan Schoppmann (UC Berkeley)
Title: the STEREO Experiment: Search for Sterile Neutrinos
Abstract: In recent years, two unsolved anomalies have appeared from the study of reactor neutrinos: the reactor antineutrino anomaly being related to the absolute neutrino flux, and the energy spectral shape anomaly. By conducting measurements of reactor neutrinos at very short baselines from a highly enriched uranium reactor, both anomalies can be addressed simultaneously.
STEREO is a liquid-scintintillator-based experiment located at a short ~10 m baseline from the ILL research reactor in Grenoble, France. Its primary objective is the search for energy and baseline dependent disappearance patterns of reactor neutrinos, which would indicate that the reactor antineutrino anomaly could be caused by neutrino oscillations towards sterile neutrinos. Its second objective is to investigate whether highly enriched uranium reactors show the same energy spectral distortions of neutrinos as lowly enriched reactors. Due to the small overburden of 15 m.w.e. and the high ambient neutron flux in the reactor hall, STEREO’s scintillator has to meet special requirements in terms of particle identification and discrimination.
In this presentation, latest results of the STEREO experiment regarding its oscillation, absolute rate, and spectral shape analyses using 179 days of reactor-on data are discussed. A highlight is set on STEREO’s liquid scintillator and its particle ID capabilities.
