Abstract
The XMASS project utilizes ultrapure liquid xenon and aims to detect pp and 7Be solar neutrinos by means of ν e e scattering. It requires low background and a low threshold, which will also enable us to search for dark matter in the Galactic halo. By using a prototype detector, we have confirmed its feasibility to realize low background and low threshold. We have estimated the sensitivity of an 800-kg liquid-xenon detector for a dark matter search experiment based on the experimental results.
