顶色辅助的人工色理论中荷电的Top介子在LC实验中对顶夸克产生的修正

Charged Top-Pions Corrections to the Top Quark Production at LC in TC2 Theory

讨论了顶色辅助的人工色理论预言的赝标量Ｇｏｌｄｓｔｏｎｅｓ粒子（ＴＣ介子和 Ｔｏｐ介子）在ＬＣ实验中对顶夸克产生的贡献，发现Ｔｏｐ介子对顶夸克产生截面 σ_的贡献是主要的，在大部分参数空间中荷电 Ｔｏｐ介子的贡献非常大．当取合 理的参数时，荷电 Ｔｏｐ介子对的σ_贡献可以达到 ８％左右，能够被 ＬＣ的实验探 测到．

We discuss the contributions of PGBs (technipions and top-pious) to the top quark production in TC2 theory at the high energy e+ e- linear collider (LC) experiments. We find that the corrections to the production cross section σ_ mathly come from top-pious. The corrections of the charged top-pious are significantly large in most of the parameter space. With reasonable value of the parameters, the correction to σ_ can reach about 8% which may be detected at LC experiments.
