| Abstract: | Introducing six new heavy leptons, we construct a U(3) scheme for leptons. The leptonic U(3) is exactly parallel to the hadronic U(3). One may also introduce quark-like leptonic triplets. A “natural” value of 60° emerges for the mixing angle with mw = 53 GeV in a theory of weak and electromagnetic interaction based on this U(3) symmetry. There are no neutral ΔSl = 0 neutrino currents. |
