13:30 - 15:00 Weekly Seminar (Online) Hunt for the Sterile Neutrino Dark Matter at XENON1T https://www.skyroom.online/ch/soa/weekly-seminar School ASTRONOMY Abstract The XENON1T collaboration recently reported the excess of events from recoil electrons which may be sign of a fundamental new discovery about our universe. In this talk, I will review the current status of different dark matter (DM) direct detection experiments towards ultimate DM detector. I will show that sterile neutrinos with masses around 90 keV and specific effective coupling can explain the XENON1T anomaly preserving DM astrophysical and cosmological constraints, and it possibly describes the anomalies in other experiments. At the end I will try to explain how one can be convinced that DM has been discovered or not fr ... |
