Information on precautionary site access restrictions to Fermilab's Batavia site in response to coronavirus/COVID-19
We continue to review all events currently planned for the next sixty days and organizers will be notified if their event must be canceled, postponed, or held remotely. Please, check back on Indico during this time for updates regarding your meeting specifics.
As DOE O 142.3A, Unclassified Foreign Visits and Assignments Program (FVA) applies not only to physical access to DOE sites, technologies, and equipment, but also information, all remote events hosted by Fermilab must comply with FVA requirements. This includes participant registration and agenda review. Please contact Melissa Ormond, FVA Manager, with any questions.

Jingqiang Ye, "Observation of Excess Electronic Recoil Events in XENON1T"


Abstract: Recently, the XENON1T experiment reported observation of the excess electronic recoil events over the unprecedentedly low background rate of 76 +- 2 (stats) events/(tonne x year x keV). The excess resides in (1, 7) keV region and is most prominent between 2-3 keV. In this talk, I will present the data analysis in this study and various scrutiny checks done for this excess. Several possible hypotheses for this excess will be discussed in detail as well.
