Description

Conservation laws of lepton flavors are discussed within the context of unified weak and electromagnetic gauge theories. It is shown that the present upper limit on the new (U) lepton-number violating processes U→3 charged leptons already requires the presence of a new neutral lepton in the SU(2) x U(1) theory. Some of the possibilities are discussed and the constraints implied by lowering the bounds on μ→eγ and U→3 charged leptons are pointed out. (Auth.)
