|Outline of Final Research Achievements
In order to address to one of the biggest mysteries in the universe, the dark matter, this research project has challenged two tasks: dark matter search with a large-scale experimental apparatus, and development and research of a next-generation dark matter search apparatus.
As for the first subject, in this study, we searched for the seasonal modulation signal by dark matter, which the previous research (DAMA / LIBRA) claims, and denied the result. In addition, we searched for dark matter candidates called Bosonic-Super WIMPs, and for the first time published the conclusion that "the vector type cannot be the main component of dark matter". For the second issue, we developed and improved ultra-low background technology.
