Abstract
The topcolor scenario generally predicts the existence of the neutral top-pion π0t and the nonuniversal gauge boson Z′, which have flavor changing couplings to ordinary fermions at tree-level. Taking into account the constraints of the lepton flavor violation (LFV) processes μ → eγ and μ → 3e on the relevant free parameters, we consider production of these new particles via the LFV processes eγ → τπ0t and eγ → τZ′ at the international linear e+e− collider (ILC) experiments. We find that the effective cross section for the LFV process eγ → τπ0t is smaller than 0.2fb. While, the effective cross section of the LFV process eγ → τZ′ can reach 12.2fb with reasonable values of the free parameters.
