摘要
计算了Topcolor辅助的人工色模型中的赝标哥尔斯通玻色子对超高能正负电子对撞机上的e+e- → tc( ct)过程的修正 .发现在质心能量为 s =2 0 0GeV时新物理对该过程的修正结果比标准模型的结果高出约 1个量级 .如果选取质心能量为s=50 0GeV得到的结果为σ(e+e- → tc)～ 1 0 - 37cm2 .
We calculated the Pseudo Goldstone boson correction to e +e -→c process at the energy s =500 GeV in topcolor assisted technicolor model. We find that the total contribution is larger than the standard model results by as much as 1 to 2 orders,i.e.the production cross section σ (e +e -→c) can be as large as 10 -37 cm 2 within the considered parameter space. So It may be observable at future e +e - collider.
