First Axion Results from the XENON100 Experiment
Abstract
We present the first results of searches for axions and axion-like-particles with the XENON100 experiment. The axion-electron coupling constant, , has been probed by exploiting the axio-electric effect in liquid xenon. A profile likelihood analysis of 224.6 live days 34 kg exposure has shown no evidence for a signal. By rejecting , larger than (90\% CL) in the solar axion search, we set the best limit to date on this coupling. In the frame of the DFSZ and KSVZ models, we exclude QCD axions heavier than 0.3 eV/c and 80 eV/c, respectively. For axion-like-particles, under the assumption that they constitute the whole abundance of dark matter in our galaxy, we constrain , to be lower than (90\% CL) for mass range from 1 to 40 keV/c, and set the best limit to date as well.
