| Abstract 摘要 | Neutrino-less muon to electron conversion in a muonic atom is a process of charged lepton flavor violation (CLFV). It is not allowed in the Standard Model (SM) and known to be one of the best processes to search for new physics beyond the SM. By using a highly intense muon source at J-PARC in Japan, the COMET experiment aims to search for this process with a single-event sensitivity of 3x10^{-17}. which is about 10,000 improvement over the current limit. Recently the COMET experiment has taken a staged approach. COMET Phase-I, as the first phase, aims at a single-event sensitivity of 3x10^{-15} with the partial muon beam line and a Phase-I dedicated detector. The COMET Phase-I physics run is expected to start in 2018/2019. The COMET Phase-II will follow immediately. In this talk, I will describe physics motivation of CLFV, and the details of COMET Phase-I / Phase-II together with the details of the highly intense muon beam line for COMET. |
