Abstract

There are two plans of experiments to search for muon to electron (\μ-e)\nconversion at J-PARC, which are called DeeMe and COMET. The \μ-e\nconversion is one of the charged lepton flavor violation processes. The\nprocesses are forbidden in the Standard Model, but some theories beyond the\nStandard Model predict relatively large branching ratios at orders of\n10^-12 to 10^-17. DeeMe will be conducted with a sensitivity of\n1\×10^-13 using a carbon target for 1 year, and COMET will be done with\nthat of 3\×10^-15 in Phase-I. In this article, the current status of\nthese two experiments will be presented.\n
