摘　　要：在Topcolor辅助的Technicolor(TC2)模型下,研究了γγ对撞中荷电Top-pion介子∏t-的产生过程γγ→t∏t-.研究结果表明,在一定的参数范围内,这个过程的产生截面大于10fb,如果未来直线对撞机ILC的年积分亮度可实现100fb-1,则每年可以观测到1000多个t∏t-产生事例.这意味着,在ILC上有望通过γγ→S∏t-来探测∏t-介子的产生,进而来检验TC2模型.The associated production of the charged top-pion ∏t^-,with the top quark in the framework of the topcolor-assisted technicolor（TC2）mode at the photon-photon collider was investigated.The results showed that the cross section of the process is more than 10 fb with reasonable values of the parameter.If the integrated luminosity of the future linear collider（ILC）can reach 100 fb-1 each year,more than 1 000 events can be produced each year.Therefore,it is promising to probe the charged top-pion ∏t^-,and to test TC2 model furthermore via the production process of γγ→tS∏t^-at ILC.
