On the search for muonic photons in neutrino experiments Original Research Article

Conserved muonic number may turn out to be a conserved muonic charge, coupled to muonic photons, γμ. Muons and muonic neutrinos would emit γμʹS, which might be discovered by analysing the data from the past and future high energy neutrino experiments (like CHARM 11, CCFR, CHORUS , NOMAD , etc.). There are two sources of γμʹS in these experiments: (I) internal bremsstrahlung in pion and kaon decays into μ and νμ, which provide neutrino beams; (2) external bremsstrahlung of muons in the shielding of the neutrino beam. In both cases the γμʹS would pass freely through the shielding and produce narrow muonic pairs in the neutrino detectors. These pairs could be distinguished from the trident events (P. +Z → νμ + μ+ + μ− + Z) by their kinematical properties: small p, of the muon pair, small invariant mass, etc. All the above processes are quantitatively analysed in this paper.
