Description
Weakly interacting massive particles (WIMPs) are a very popular explanation for the nature of dark matter. The XENON100 experiment and its next generation the XENON1T experiment aim for detecting WIMP-nucleon interactions using a dual phase time projection chamber (TPC) with a total liquid xenon target of 161 kg and 3500 kg, respectively.
This talk will present the most recent results of XENON100 where exclusion limits are set on several leptophillic dark matter models and on the event rate modulation of electronic recoils. Those results are in strong tension with models that explain the signal seen in the DAMA experiment by dark matter interacting exclusively with leptons.
Furthermore, the commissioning status of the XENON1T experiment and its scientific potential will be presented. Major achievements in background reduction allow to reach a sensitivity improvement by two orders of magnitude with respect to XENON100.
