A search for light dark matter in XENON10 data


XENON100 Collaboration; Angle, J; Baudis, L (2011). A search for light dark matter in XENON10 data. Physical Review Letters, 107(5):051301.

Abstract

We report results of a search for light (≲10  GeV) particle dark matter with the XENON10 detector. The event trigger was sensitive to a single electron, with the analysis threshold of 5 electrons corresponding to 1.4 keV nuclear recoil energy. Considering spin-independent dark matter-nucleon scattering, we exclude cross sections σn>7×10-42  cm2, for a dark matter particle mass mχ=7  GeV. We find that our data strongly constrain recent elastic dark matter interpretations of excess low-energy events observed by CoGeNT and CRESST-II, as well as the DAMA annual modulation signal.
