Outline of Final Research Achievements |
The proposed research project is to search for a process of charged lepton flavor violation (CLFV) of muon to electron(μ-e) conversion by the first phase of the J-PARC E21COMET experiment (COMET Phase-I), with an improved experimental sensitivity by more than hundredsover the previous experimental limit. It has been experimentally confirmed that quarks and neutrino are transformed one another. However, only CLFV has been yet to be observed, and a discovery of CLFV is considered to be one ofthe most important subjects, which potentially leadsa search to discover new physicsbeyond the Standard Model in particle physics.
