| 摘 要： | 在TC2模型下通过γγ→πt+πt-过程研究了对产生带电top-pion介子.结果表明,对于γγ→πt+πt-过程,其产生截面能够达到100fb量级.在年积分亮度为500fb-1的高能直线对撞机上,通过γγ→πt+πt-过程,每年能收集到数以千计的πt+πt-事例.有如此多的事例数和干净的背景,带电top-pion介子应该能在光子对撞机上被观测到.因此,该研究能帮助寻找带电top-pion介子,并为检验TC2模型提供很好的理论依据.

| Abstract: | The pair production of charged top-pion is studied via γγ→π+tπ-tprocess in the framework of the top-color-assisted technicolor(TC2) mode.The study shows that the cross-section reaches to the level of hundreds of fb.With the yearly integrated luminosity of 500 fb-1 expected at the high-energy linear colliders,the research could collect thousands of charged top-pion of events via the process of γγ→π+tπ-t.Due to these large number of events and the clean standard model(SM) background,the charged top-pion should be observabled at the photon-photon colliders.Therefore,this paper can help to search for charged top-pion,and furthermore,to test the TC2 mode1. |
