VIRTUAL SEMINAR Special INPA / Research Progress Meeting, Friday, July 17, 2020 – Michelle Galloway (University of Zurich)
July 17, 2020 @ 10:00 am - 11:00 am
Speaker: Michelle Galloway (University of Zurich)
Title: Observation of excess electronic recoil events in XENON1T
Abstract: A search for new physics with XENON1T revealed an excess of electronic recoil events in the (1 – 7) keV region, favoring signal over background with significances of 3.5 sigma for solar axions/ALPs, 3.2 sigma for an enhanced neutrino magnetic moment, and 3.0 sigma global (4.0 local) for bosonic dark matter with a peak at 2.3 +- 0.2 keV (68% C.L.). Additionally, a previously undetected tritium component, favoured at 3.2 sigma over known backgrounds, can neither be confirmed nor excluded. I will provide an overview of the XENON1T detection and analysis methods for this search, a characterization of the excess events, and present results for both possible backgrounds and potential new physics.
