The muon anomalous magnetic moment, $(g-2)_{\mu}$, and the electric dipole moment (EDM) are sensitive probes of physics beyond the Standard Model (SM). Recent measurements of $(g-2)_{\mu}$ show a tension with the SM prediction based on electron-positron collision data, while calculations based on lattice QCD are in better agreement with the experimental value. Clarifying this discrepancy is...

The ultra-slow muon (USM), developed for the J-PARC muon g-2/EDM experiment, is produced by laser ionization of thermal muonium using 122 nm and 355 nm laser pulses, a process known as muon cooling. Since late 2025, two beam tests have been conducted using the new high-intensity surface muon beamline dedicated to the J-PARC muon g-2/EDM experiment. During these beam tests, extensive studies of...

The muEDM experiment at the Paul Scherrer Institute (PSI) aims to measure the muon electric dipole moment (EDM) with unprecedented sensitivity, targeting a precision of σ($d_\mu$) = 6 × 10⁻²³ e·cm, which represents an improvement by three orders of magnitude over the current limit established by the muon g−2 experiment at Brookhaven National Laboratory (BNL). Central to this effort is the muon...

We propose a next-generation precision measurement of the muon anomalous magnetic moment (muon g−2), at the High Intensity Heavy-Ion Accelerator Facility (HIAF) in China. The project, named CANTON-μ (Coherent Anomalous magNetic momenT ObservatioN with muon), represents the first muon g−2 experiment aimed at surpassing Fermilab precision. It introduces novel approaches based on HIAF's intense...
