顶色辅助的多标度人工色理论对稀有过程e^+e^-→s的单圈效应

One Loop Effects to the Process e^+ e^-→s in Topcolor-Assisted Multiscale Technicolor Model

讨论了顶色辅助的多标度人工色理论预言的赝标哥尔斯通玻色子（ｔｅｃｈ－ ｎｉｐｉｏｎｓ，ｔｏｐ－ｐｉｏｕｓ）对稀有过程ｅ＋ｅ－→ｂｓ的单圈效应，计算了该过程在ＬＥＰⅡ上 的产生截面，得到较标准模型预言值要大一个数量级的数值结果．并进一步讨 论了在Ｂ介子工厂上探测此稀有过程的可能性．

We calculated the Pseudo-Goldstone bosons (technipions, top-pious) corrections to the cross-section a of the process e+ e- →bs in topcolor-assisted multiscale technicolor model at LEP Ⅱ energy region. Our results show that, with reasonable value of the parameters, the cross-section is one order larger than that predicted by the standard model. We discussed the possibility of detecting this rare event at the B-factoly.
