Direct Dark Matter search with the XENON program

Abstract: We present the most recent results from XENON100, the current phase of the XENON dark matter search program. XENON100 is a dual phase time-projection chamber operated at the Laboratori Nazionali del Gran Sasso (LNGS) whose ultra-low electromagnetic background, about 5 x 10^-3 events/(kg x day x keV), allowed to set the most stringent limit to date, excluding WIMP-nucleon spin-independent interaction down to cross-sections of 2 x 10^-45 cm^2 for a 55 GeV/c^2 mass at 90% confidence level and 3.5 x10^-40 for 45 GeV/c^2 in the spin-dependent interaction with neutrons. We also introduce the status and physics goal of XENON1T, the next phase of the program, which will be able to achieve sensitivity down to 2 x 10^-47 cm^2 for a WIMP of 50 GeV/c^2.
