Status of the COMET Experiment

The COMET experiment aims to search for the neutrinoless coherent transition of a muon to an electron in the field of an aluminum nucleus, which violates the lepton flavor conservation and has never been observed yet thus far. The experiment takes place at J-PARC with single event sensitivities of orders of 10−15 and 10−17 in the Phase-I and Phase-II, respectively. The ambitious goals of the COMET experiment are achieved by realizing a high-quality pulsed beam and unprecedentedly powerful muon source. The construction of a new beamline, superconducting magnets, detectors and electronics is intensively in progress towards the forthcoming Phase-I measurement. An overview and recent status of the COMET experiment are presented.
