Probing heavy neutrinos in the COMET experiment
Probing heavy neutrinos in the COMET experiment
We argue that the COMET experiment—a dedicated experiment for the |$\mu $|–|$e$| conversion search—has a good potential to search for heavy neutrinos in the mass range |$1\,{\rm MeV} \lesssim M \lesssim 100\,{\rm MeV}$|. The stopped muons captured by the target nuclei or decaying in orbit efficiently produce heavy neutrinos via …
