根据最小标准模型及双Higgs二重态的扩展标准模型理论,计算了LEPⅡ以及NLC能量下e+e—→bb Z0 和 tt－Z0的总截面和微分截面以探求Higgs粒子的观测效应.我们发现,只要Higgs粒子的质量MH≤140GeV,对e+e—→bb Z0的测量就能清楚地提供Higgs粒子的信息.然而对e+e—→tt－Z0,不论Higgs粒子是轻或重,它的效应都被淹没在弱电过程的本底中,没有观测的可能.

在Topcolor辅助的多标度人工色(TOPMTC)模型框架下计算了扩充人工色(ETC)相互作用对顶夸克对产生过程中CP破坏参数δ的贡献(δ=σ[e–e→t(–)–t(–)]–σ[e–e→t(+)–t(+)]/σ(e–e→t–t)).计算结果表明,对于合理的参数取值,ETC相互作用可对参数δ产生较大的修正(8.65×10－3≤δ≤1.09×10－2).期望在将来的NLC实验中能观测到此修正效应.
