About the INPA Seminars

All seminars are on Fridays (unless otherwise noted) and start at 12:00 (noon) with a brief presentation of the weekly scientific news. Typically the talks end by 13:00. The seminars take place in Bldg. 50A, room 5132.

The committee members are:

The following Seminar schedule for the Institute for Nuclear and Particle Astrophysics is tentative. The seminar becomes final usually a few days before the Friday of the talk.

VIRTUAL SEMINAR Special INPA / Research Progress Meeting, Friday, July 17, 2020 – Michelle Galloway (University of Zurich)

July 17 @ 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.

Also, on Fridays from 1:00 pm to 2:00 pm you are welcome to join the INPA Speaker for a brown-bag lunch in the small Pers Hall conference room, 54-130B.

INPA Tea Series

The Physics and Nuclear Science Divisions have together been leaders in revolutionary changes in our understanding of neutrinos and cosmology. Everyone is welcome to attend the open forum. Tea and light refreshments will be served.
