SUMMARY:INPA Seminar - Chiara Capelli (University of Zurich)
DESCRIPTION:Speaker: Chiara Capelli (University of Zurich)\nTitle: Data analysis at high-energies for the XENON1T experiment and light calibration system of XENONn \nAbstract: The XENON1T experiment searches for Weakly Interacting Massive Particles (WIMPs) with a dual-phase xenon Time Projection Chamber (TPC). To extend its physics reach\, the efforts of the XENON collaboration are directed toward exploring other detection channels. For this purpose\, considerable work on the signal reconstruction and data analysis has been done to extend the available energy range up to 3\\,MeV\, two orders of magnitude higher than the standard WIMP analysis. This would allow one to search for the neutrinoless double beta decay (0$\nu\beta\beta$) of $^{136}$Xe\, which is fundamental to probing the Majorana nature of neutrinos and solving the hierarchy problem. The achievements and future prospects for the high-energy analysis with dual-phase TPCs will be presented. Furthermore\, the upcoming XENONnT experiment\, an upgrade of XENON1T with a larger TPC and reduced background\, is expected to start taking data in 2020. Its main goal is to increase the sensitivity to WIMPs by an order of magnitude compared to the current best limit\, as well as improving the search for 0$\nu\beta\beta$. An overview of the new systems\, with attention on the light calibration of the 494 photomultiplier tubes (PMTs) will be also presented. \n
