在CMS上的荷电MSSM希格斯玻色子:到达和参数依赖性

Charged MSSM Higgs Bosons at CMS: Reach and Parameter Dependence

S. Heinemeyer, A. Nikitenko, G. Weiglein

摘要:

我们回顾了在30 fb^-1的CMS实验中,对M_H+ < m_t和M_H+ > m_t两种情况下带电MSSM希格斯玻色子的5 σ发现等值线的分析。最新的结果CMS实验灵敏度的基础上充分的模拟研究相结合的最先进的理论预测MSSM希格斯玻色子的生产和衰变特性。特别关注的是把超对称性参数依赖的5西格玛轮廓。mu的变化可以使tan_beta中的预期发现范围偏移达Delta tan_beta = 40。我们还讨论了信号截面和分支比计算的各种理论不确定性。为了在大型强子对撞机上对带电的MSSM希格斯玻色子的信号做出可靠的解释,必须大大减少相关理论的不确定性。

英文摘要:

We review the analysis of the 5 sigma discovery contours for the charged MSSM Higgs boson at the CMS experiment with 30 fb^-1 for the two cases M_H+ < m_t and M_H+ > m_t. Latest results for the CMS experimental sensitivities based on full simulation studies are combined with state-of-the-art theoretical predictions of MSSM Higgs-boson production and decay properties. Special focus is put on the SUSY parameter dependence of the 5 sigma contours. The variation of mu can shift the prospective discovery reach in tan_beta by up to Delta tan_beta = 40. We furthermore discuss various theory uncertainties on the signal cross section and branching ratio calculations. In order to arrive at a reliable interpretation of a signal of the charged MSSM Higgs boson at the LHC a strong reduction in the relevant theory uncertainties will be necessary.
