Top-Higgs和Top-Charm在高能正负电子对撞机上的联合产生

Associated Production of Top-Higgs with Top-Charm at the High Energy e^+e^- Colliders

在顶色辅助的人工色(TC2)模型框架下,研究了top-Higgs和t—c夸克的联合产生过程e+e-→tcht0.结果显示此过程的产生截面在合理的参数空间内可达到10fb,在高能直线对撞机(LC)上每年可产生几百个事例.通过此过程可用来探测top-Higgs.

We study a top-Higgs production process e^＋e^- →tc^0ht^0 in the topcolor assisted technicolor（TC2） model. The studies show that the production cross section of e^＋e^- →tc^0ht^0 is at the order of magnitude 10fb in the reasonable parameters space of TC2 model. A few hundred events of top-Higgs can be produced each year at the high energy linear e^＋e^- colliders（LC）. The top-Higgs may be directly observed via this process.
