Abstract

We discuss conservation laws of lepton flavors within the context of unified weak and electromagnetic gauge theories. We show that the present upper limit on the new (U) lepton-number violating processes U→3 charged leptons already requires the presence of a neutral lepton in the SU(2) ⊗ U(1) theory. We discuss some of the possibilities and point out the constraints implied by lowering the bounds on μ→eγ and U→3 charged leptons.
