希格斯三重态模型中三体希格斯玻色子在ILC上的产生

Triple Higgs Boson Production in the Higgs Triplet Model at the ILC

在希格斯三重态模型(HTM)的理论框架下,研究了带电希格斯玻色子对(H~±,H^(±±))与中性的希格斯玻色子h在国际线性对撞机(ILC)上的两个协同产生过程:e-e+→h H^+H^-和e-e+→hH^(++)H^(--),并计算了它们的产生截面,讨论了相关的标准模型背景.结果表明,在合理的参数空间内,这两个过程的产生截面分别达到几个fb和数十fb的量级,在未来的ILC实验上可能通过这些过程探测到HTM中带电标量粒子H~±和H^(±±)的信号.

In the framework of the Higgs triplet model（ HTM）,triple Higgs production at the International Linear Collider（ ILC） was studied： e-e＋→h H＋H-and e-e＋→h H＋ ＋H--. The numerical results showed that,with reasonable parameter values,the values of the cross-sections for two processes can reach the level of several fb and tens of fb,respectively. Due to the small SM background,the possible signals of H±and H± ±might be detected via these processes in the future high-energy linear-collider experiments.
