摘　　要：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^- → t^bπt^-（^tbπt^＋）. At a γγ collider, it can be produced via the processes γγ →t^bπt^-（t^-bπt^＋）. The cross section can reach to a few of fb depending on the mass of the charged top-pion.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.
