XMASS: Recent results and status
  The XMASS project is designed for multiple physics goals using
highly-purified liquid xenon scintillator in an ultra-low radioactivity
environment. As the first stage of the project, the detector with 835 kg of
liquid xenon was constructed and is being operated. In this paper, we present
results from our commissioning data, current status of the experiment, and a
next step of the project.
