| Summary: | There are two plans of experiments to search for muon to electron ($\mu$-$e$)
conversion at J-PARC, which are called DeeMe and COMET. The $\mu$-$e$
conversion is one of the charged lepton flavor violation processes. The
processes are forbidden in the Standard Model, but some theories beyond the
Standard Model predict relatively large branching ratios at orders of
$10^{-12}$ to $10^{-17}$. DeeMe will be conducted with a sensitivity of
$1\times10^{-13}$ using a carbon target for 1 year, and COMET will be done with
that of $3\times10^{-15}$ in Phase-I. In this article, the current status of
these two experiments will be presented. |
