Abstract

We consider the lepton-flavor violating(LFV) processes liljγl_{i}\to l_{j}\gamma in the framework of topcolor assisted technicolor(TC2) models. We find that the new gauge boson ZZ^{\prime} predicted by TC2 models can give significantly contributions to these processes via the flavor changing couplings. The present experimental bound on the LFV process μeγ\mu \to e\gamma gives severe constraints on the TC2 models. In the case that the ZZ^{\prime} mass MZM_{Z} is consistent with other experimental constraints, we obtain constraints on the lepton mixing factors KτμK_{\tau\mu} and KτeK_{\tau e}. The future LFV experiments will be probe of the TC2 models.
