Abstract: Precise measurements using muon beam are promising approaches to
search for new physics beyond the standard model of particle physics. One of
such experiments is the measurement of muon anomalous magnetic moment (g-
2). Muon g-2 anomaly is one of the most well-known anomalies in particle
physics. Another important experiment is the search for the muon electric dipole
moment (EDM), which can probe CP violation in the lepton sector of the
second generation of the standard model.
A new experiment to measure the muon g-2 and search for muon EDM is
underway at J-PARC. This experiment is unique in that it cools the muon beam
to improve the beam quality, enabling the stable storage of muons within a
magnetic field to precisely measure their spin precession. Thermal muons will be
produced through resonant multi-photon ionization of thermal muonium using
high-energy VUV and UV lasers, after which these muons will be accelerated to
200 MeV by linear RF accelerators.
In this talk, I will provide an overview of our experiment and its current
status, including the recent milestone of achieving the first RF-acceleration of
cooled muons. I will also discuss the future prospects of the experiment."
