COMET (Coherent Muon to Electron Transition) is a nuclear physics experiment in
J-PARC,
Tokai, Japan.[1][2] In contrast to the usual
muon decay to an
electron and
neutrino, COMET seeks to look for neutrinoless muon to electron conversion, where the electron flies away with an energy of 104.8 MeV. Muon to electron conversion is not forbidden in the
Standard Model but the branching ratio is about considering
neutrino oscillations. In
beyond the Standard Model approaches the muon to electron conversion process can be as high as e.g. via the
supersymmetric.
COMET will be[when?] using a new beamline connecting the J-PARC main ring and the J-PARC Nuclear and particle Physics Experimental Hall (NP hall).
The current[when?] spokesperson is
Kuno Yoshitaka alongside project manager Mihara Satoshi.[citation needed] The collaboration consists of universities coming from 15 countries.[3]
