New results from the XENON1T experiment and status of XENONnT [IRMP Colloquium] [BEL-center]

by Laura Baudis (UZH)


The XENON1T experiment at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy, acquired data until the end of 2018. At its core, it housed a two-phase (liquid/gas) xenon time projection chamber with 2 tons (3.2 tons in total) of liquid xenon. Built to primarily search for Weakly Interacting Massive Particles as dark matter candidates, it was also sensitive to other rare interactions, due to its unprecedented low background noise. Recently, the XENON collaboration reported an excess of electronic recoil events at low energies. After an introduction to the liquid xenon technology, I will discuss the new XENON1T results and its various interpretations. I will end with presenting the status of XENONnT, which will operate a new TPC with 6 tons of liquid xenon (8.4 tons in total), currently in commissioning stage at LNGS.
