Selected Presentations

A review talk on particle physics experiments using muons at international conferences focused on high-energy physics. It introduced representative experiments and their results for both rare decay searches and precision measurements, and discussed ongoing and planned new experiments.

A presentation on microwave spectroscopy of muonium and the development of a muonium atom interferometer aimed at precise determination of the muon mass. It introduced the results obtained in the MuSEUM experiment and presented a proposal for measuring the muon's mass using the photon recoil shift.

A presentation on the development of the ultra-slow muon beam and its application in thin-film research at an international conference on materials science. It reported on the current status of ultra-slow muons at J-PARC MUSE, the results obtained through commissioning , and the progress of initial scientific measurements.

A talk on laser spectroscopy of the hyperfine structure in the ground state of muonic hydrogen atoms and relevant studies using muonic atoms. Particularly a searcg for parity non-conservation effects in muonic atoms was introduced. It reported on the development of instruments, preliminary experiments, and preparations for the spectroscopy experiment.

A presentation on microwave spectroscopy of muonium conducted in the MuSEUM experiment. It utilized the high-intensity pulsed muon beams at J-PARC MUSE to measure the hyperfine structure in the ground state of muonium. The presentation reported on the experiment's overview, the results obtained in a near-zero magnetic field experiment, and the status of preparations for measurements aiming at the highest precision in high magnetic fields.
