| Research Abstract |
”Why there is no anti-matter in the Universe?” One of the keys to answer this question is to observe the neutrino-less double beta decay . Many experiments to search for the decays are running at the underground laboratories although no events have been found. The next-generation experiments which have better sensitivities are in the R&D stage. We have developed the new methods to increase the energy resolution of our detector to improve the sensitivity. The experiments using the prototype detector and the simulation show that the enough performance will be achieved in our next-generation detector.
