Description
Results of various WIMP direct dark matter searches using full data set of XMASS-I are reported. The XMASS-I is multi-purpose experiment using single phase liquid xenon at the Kamioka Observatory (2700 m.w.e.) in Japan. Stable XMASS-I data taking accumulated a total live time of 1590.9 days between Nov. 20, 2013 and Feb. 1, 2019.
The analysis thrshold was 1.0 keV (for electron recoil) for whole data set, and 0.5 keV for latter half of data set owing to improvement of a trigger system.
We will describe results from searching for WIMP signal in the detector's fiducial volume (97 kg) and WIMP induced annual modulation signatures in the detectos's whole target volume (832 kg).
