Abstract

The XENON100 experiment is the second phase of the XENON program for the direct detection of the dark matter in the universe. The XENON100 detector is a two-phase Time Projection Chamber filled with 161 kg of ultra pure liquid xenon. The results from 224.6 live days of dark matter search with XENON100 are presented. No evidence for dark matter in the form of WIMPs is found, excluding spin-independent WIMP-nucleon scattering cross sections above 2 ×\times 1045^{-45} cm2^2 for a 55 GeV/c2^2 WIMP at 90% confidence level (C.L.). The most stringent limit is established on the spin-dependent WIMP-neutron interaction for WIMP masses above 6 GeV/c2^2, with a minimum cross section of 3.5 ×\times 1040^{-40} cm2^2 (90% C.L.) for a 45 GeV/c2^2 WIMP. The same dataset is used to search for axions and axion-like-particles. The best limits to date are set on the axion-electron coupling constant for solar axions, gAeg_{Ae} < 7.7 ×\times 1012^{-12} (90% C.L.), and for axion-like-particles, gAeg_{Ae} < 1 ×\times 1012^{-12} (90% C.L.) for masses between 5 and 10 keV/c2^2.
