The article reviews the conditions for lepton-flavor conservation in leptonic interactions. are similar to those developed quark sector. For neutrinos mass eigenstates unitary superpositions of flavor states which together with small differences produce neutrino oscillations. A new property is fact that their masses very suppressing couplings neutral scalar fields. results demonstrated several ...
