Description
The COMET experiment at J-PARC searches for the charged-lepton-flavour-violating process of coherent muon-to-electron conversion in a muonic atom, $\mu^- N \to e^- N$, with a target single-event sensitivity of $\mathcal{O}(10^{-15})$ during Phase I, which is scheduled to begin in 2028. The experiment employs an 8 GeV bunched slow-extraction proton beam from the J-PARC Main Ring, which is transported via a dedicated beamline to the experimental facility. Superconducting solenoidal magnets efficiently capture and transport low-momentum muons to the stopping target. A suite of detector systems is being developed to identify signal electrons with high precision while suppressing background, including cosmic rays, using a dedicated Cosmic Ray Veto (CRV) system in which RPCs play a key role.
This contribution will present an overview of the current status of the COMET project, outline the roadmap toward Phase I operation, and highlight opportunities for collaboration and future contributions.
