Description
In 2021, the anomalous magnetic moment of the muon, a_µ = (g_µ-2)/2, was measured at the Fermilab National Accelerator Laboratory (FNAL) with a precision of 0.46 ppm. This measurement result is consistent with the previously value measured more than a decade ago at the Brookhaven National Laboratory (BNL), and the deviation from the Standard Model (SM) prediction has been reported with a significance of 4.2 standard deviations. This suggests the potential existence of new physics beyond the SM, but it needs to be verified through measurements employing different methods. The muon g-2/EDM experiment at J-PARC aims to measure a_µ and the electric dipole moment (EDM) using a low-emittance muon beam realized through the acceleration of thermal muons and silicon tracking detectors, employing a different approach from the BNL and FNAL experiments. This presentation provides an update on the current status of each experimental component.
