| Outline of Final Research Achievements |
Majorana neutrinos could play the central role in explaining the origin of our matter-dominated universe and light neutrino mass. Neutrinoless-double-beta decay is only unique scheme to study Majorana neutrino. We have developed several scheme to improve KamLAND-Zen sentivity. KamLAND-Zen is one of the experiments to search for neutrinoless-double-beta decay. We experimentally demonstrated two unique ideas to reduce backgrounds; scintillating balloon and imaging camera.
