Recent results and status of the XENON program
Résumé
The XENON program aims at the direct detection of dark matter WIMPs with liquid xenon as tar- get and detecting material. With detectors of increasing ta rget mass and decreasing background, XENON has achieved competitive limits on WIMP-nucleon inte raction couplings, but also on axions and axion-like particles. The detector has been ongo ing at the Laboratori Nazionali del Gran Sasso in Italy since 2009 with a dual phase (liquid-gas) xenon Time Projection Chamber and a total mass of 161 kg of liquid xenon. The most recent resu lts will be presented. Current run mainly focuses on additional calibration for the low ene rgy response of the detector and the validation of new calibration techniques in view of the next generation experiment, XENON1T. XENON1T will be the first experiment to use liquid xenon in a ti me projection chamber at the ton scale. It is designed to achieve two orders of magnitude high er sensitivity than the current best limits.
