Topic: The recent result of XMASS Experiment

Abstract:

XMASS is a multi-purpose experiment using a single-phase liquid-xenon scintillator detector located underground at Kamioka Observatory in Japan. With the commissioning data from December 2010, we conducted various dark matter searches such as light WIMPs, WIMP-129Xe inelastic scattering, and bosonic super-WIMPs. After a successful refurbishment to reduce background events, we are continuously taking data since November 2013. With these long-term data, we have searched for dark matter in a fiducial volume and for annual modulation caused by dark matter with masses down to Sub-GeV range. The XMASS detector is also capable of pursuing various researches in particle and astroparticle physics such as supernova neutrino observation, solar axion search, and double electron capture search. A recent development of beta ray and gamma ray separation by waveform enhances physics sensitivities. In this talk, the recent physics results from the XMASS data will be presented.
