COMET muon conversion experiment in J-PARC

  • 1Institute for Basic Science (IBS), South Korea

COMET is an experiment at J-PARC, Japan, which will search for neutrinoless conversion of muons into electrons in the field of a nucleus (μ− + N → e− + N); a lepton flavor violating process. The experimental sensitivity goal for this process is order of 10^−15 for Phase-I
and 10^-17 for Phase-II experiment, which is a factor of 100 to 10,000 improvements correspondingly over existing limits. Recent progresses in facility and detector development are presented, along with COMET Phase-I and Phase-II experimental schedule.
