  • Abstract There are many models beyond the standard model predicting the existence of non-universal gauge bosons Z ′, which can give rise to very rich phenomena. We calculate the contributions of the non-universal gauge bosons Z ′, predicted by topcolor-assisted technicolor (TC2) models and flavor-universal TC2 models, to the lepton flavor-violating tau decays τ → l i γ and τ → l i l j l k . We find that the branching ratio B r ( τ → l i l j l k ) is larger than that of the process τ → l i γ in… CONTINUE READING
