Search for dark matter with the XENON100 experiment — •Teresa Marrodán Undagoitia — MPIK Heidelberg
The XENON100 experiment, located at the Italian Gran Sasso Laboratory, aims at the direct detection of weakly interacting dark matter particles via their elastic scattering off xenon nuclei. The detector is a liquid-gas time projection chamber built out of ultra radio-pure materials. In 2012, results from 225 live days data at 34kg fiducial mass were released, leading to the best sensitivity for WIMP masses above 8 GeV/c2. After a brief review of the detector and its main components, the data analysis will be described and the latest results will be presented. The calibration procedures to determine the signal and background regions and the energy scales will be discussed, as well as laboratory activities to measure the electronic recoil scale in liquid xenon. Finally, the developments towards the construction of XENON1T will be presented.
