摘要 在顶色辅助的人工色模型下,深入研究了中性top-pion的产生过程e+e-→veve-Πt0.详细分析了质心能量与电子的极化状态对产生截面的影响.研究结果表明,在各种中性top-pion的产生道中,由于背景清晰,味改变道t-c是探测中性top-pion的最好的道. In the framework of top-color-assisted Techinicolor(TC2) model, we study the neutral top-pion production process e^+e^-→veveⅡt^0 in detail. We analyze the influence of √S and the polarization of the electron beams on the cross section. The paper also shows that, among the various decay modes, flavor-changing mode Ⅱt^0→tc is the best channel to detect the neutral top-pion because of the clean background.
