Light WIMP search in XMASS
  A search for light dark matter using low-threshold data from the single phase
liquid xenon scintillation detector XMASS, has been conducted. Using the entire
835 kg inner volume as target, the analysis threshold can be lowered to 0.3
keVee (electron-equivalent) to search for light dark matter. With low-threshold
data corresponding to a 5591.4 kg$\cdot$day exposure of the detector and
without discriminating between nuclear-recoil and electronic events, XMASS
excludes part of the parameter space favored by other experiments.
