Lepton flavor violating signals of the neutral top-pion in future lepton colliders

The presence of the top-pions pi(0,+/-)(t) in the low-energy spectrum is an inevitable feature of the topcolor scenario. Taking into account the constraints of the present experimental limit of the lepton flavor violating (LFV) process mu -> e gamma on the free parameters of topcolor-assisted technicolor models, we study the contributions of the neutral top-pion pi(0)(t) to the LFV processes mu(+)mu(-)->tau mu (or tau e), gamma gamma ->tau mu (or tau e), e(+)e(-)->tau mu, and e gamma -> e pi(0)(t)-> e tau mu(e) via the flavor changing couplings pi(0)(t)l(i)l(j) and discuss the possibility of searching for the LFV signals via these processes in future lepton colliders.
