Abstract

The COMET experiment at J-PARC, Japan, aims to search for muon to electron conversion with aluminium nuclei, achieving a sensitivity four orders of magnitude higher than the current upper limit at a 90% confidence level. The proton beam line has recently been completed, and muons have been successfully transported through the curved solenoid in the Phase-alpha of the experiment. In this paper, we will present preliminary results from the Phase-alpha beam measurement, the status of the intermediate sensitivity experiment (COMET Phase-I), and the ultimate goal of COMET Phase-II.
