On the production of a lepton pair in the collision of ultrarelativistic neutral particle with nonzero magnetic moment with nuclei

Explicit formulas which describe muon pair production in reaction gamma nu --> mu (+) mu (-) nu through neutrino magnetic moment are obtained and used to derive in the leading approximation cross section of muon pair production in nuN-scattering due to neutrino magnetic moment. This cross section appears to be proportional to log(4) E-nu. Comparison with experimental data on tridents production provides an upper bound mu (nu mu) < 4 x 10(-8) (B), which is approximately two orders of magnitude weaker than that from vile elastic scattering data.
