摘要
讨论计算了TC2模型预言的Top介子在HERA和构想中的THERA对撞机上对t道eq→et过程中的单顶夸克产生的贡献 .结果表明 :中性Top介子对ec→et过程中的单顶夸克产生有较大的贡献 .在绝大部分参数空间内 ,过程的产生截面在 1— 6pb范围内 ,因此 。
We consider the contributions of the physical top-pions predicted by topcolorassisted technicolor (TC2) models to the single top production via the t-channel process eq→et at the HERA and THERA colliders. We find that the neutral top-pion can generate large contributions to the process ec→et. In most of the parameter space, the production cross section is in the range of 1—6pb. The signals of the neutral top-pion can be studied in the HERA and THERA colliders.
