摘　　要：除了类标准模型中的希格斯粒子,最小Higgs模型(LH)还预言了带电的标量粒子Ф±的存在.研究了该带电的标量粒子与单个顶夸克在大型强子对撞机(LHC)上的联合产生过程.计算结果表明,在大部分参数空间内产生截面在0.1 fb量级,很难通过该过程探测带电标量粒子的信号,但为区分其他新物理模型中的带电标量粒子,如最小超对称(MSSM)模型中的带电Higgs玻色子提供一个途径.将来的LHC实验可以通过该过程进一步检验或排除LH模型.Besides the SM-like Higgs boson,the littlest Higgs model （LH） also predicts the existence of a charged scalarφ^±.The associated production of the charged scalar with a single top quark at the Large Hadron Collider （LHC） In this paper was studied.The results showed that in the most of the parameter spaces,the production cross section is smaller than 0.2 fb and thus is difficult to be detected.However, it can open a window to distinguish the charged Higgs in other new physics models,such as the MSSM.Future LHC experiment can further test or exclude the LH model.
