ON THE SEARCH FOR MUONIC PHOTONS IN NEUTRINO EXPERIMENTS

Conserved muonic number may turn out to be a conserved muonic charge, coupled to muonic photons, gamma(mu). Muons and muonic neutrinos would emit gamma(mu)'s, which might be discovered by analysing the data fro m the past and future high energy neutrino experiments (like CHARM II, CCFR, CHORUS, NOMAD, etc.). There are two sources of gamma(mu)'s in t hese experiments: (1) internal bremsstrahlung in pion and kaon decays into mu, and nu(mu) which provide neutrino beams; (2) external bremsst rahlung of muons in the shielding of the neutrino beam. In both cases the gamma(mu)'s would pass freely through the shielding and produce na rrow muonic pairs in the neutrino detectors, These pairs could be dist inguished from the trident events (nu(mu)+Z --> nu(mu)+mu(+)+mu(-)+Z) by their kinematical properties: small p(t) of the muon pair, small in variant mass, etc. All the above processes are quantitatively analysed in this paper.
