SUMMARY:JOINT INPA/RPM Seminar | Michelle Galloway (University of Zurich) "Observation of excess electronic recoil events in XENON1T"
DESCRIPTION:Abstract:  \nA 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. \nhttps://lbnl.zoom.us/j/98002426771?pwd=R3dtTFhmb0ZyR0ZHV1E5amZCcnFBZz09 \nMeeting ID: 980 0242 6771\nPassword: 531232
