Abstract
We study the charged top-pion in the topcolor assisted technicolor model(TC2), and calculate the production of charged top-pion at e+e- and γγ colliders. At an e+e- collider, charged top-pion can be produced via the processes e+e- →tbπt-(tbπt+).At a γγ collider, it can be produced via the processes γγ → tbπt-(tbπt+). The cross section can reach to a few of fb depending on the mass of the charged top-pion. -
