Electronic-Recoil Excess in XENON1T
Sara Diglio (Subatech)
Description :

With the lowest background level ever reached by a liquid xenon time
projection chamber, XENON1T proved to be the most sensitive WIMP dark
matter direct detection experiment on earth. Despite being primarily
designed to search for nuclear recoils between WIMPs and xenon atoms,
the unprecedented low electron recoil background of 76 ± 2 stat
events/(tonne × year × keV) between 1–30 keV, made the XENON1T
experiment suitable also to explore new parameter space for
electronic-recoil channels.
In this talk, I will review the XENON1T detection principles before
focusing on the recently observed electronic recoil excess in the (1 -
7) keV region. I will discuss the different interpretations of this
excess, provide details on the analysis, and cross-checks of our results.
