| Outline of Final Research Achievements |
The MEG experiment, which searches for the lepton flavor violating muon decay, mu -> e gamma, presented the final result with the full data set on March 2016. Our group promotes the MEG II experiment with a goal of one order of magnitude improvement from the MEG experiment. Especially, we are aiming at the dramatical performance improvement of the gamma detector with a new photon sensor and with a high granularity scintillation light readout.
In this research, we completed the development of the new photon sensor, MPPC which can be used in the liquid xenon, and succeeded in making the large amount of the sensors for the MEG II experiment. This will open the possibility that other projects can use this photon sensors for different purposes.
