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-violation tau decays τ →l iγ and τ →l il jl k. We find that the branching ratio Br(τ →l il jl k) is larger than that of the process τ →l iγ in all of the parameter space. Over a sizable region of the parameter space,we have Br(τ →l il jl k)～10^－8,which may be tested in the future experiments.
