Simulated photon neutrino electromagnetic interaction

A P and generalized C P conserving schemes have been proposed for coupling off mass shell photons to neutrino in a way where photon decouples from neutrino on mass shell. It is found that the mean square electric and magnetic charge radii of neutrino comes out to be: < r2 > e approx. 10-31 cm2 and < r2 > m approx. 10-2 < r2 > e, respectively, the former in conformity with the experimental evidences.
