Howard E. Haber, Oscar Stal

摘要:

本文介绍了一种利用新的“混合”基研究具有软破缺Z_2对称性的CP守恒的一般2HDM模型的参数空间的策略。在此基础上,输入参数是观测到的类标准模型(SM)希格斯玻色子的质量及其与矢量玻色子对的耦合强度的测量值,第二CP偶希格斯玻色子的质量,中性希格斯真空期望值的比率,以及三个额外的无量纲参数。使用混合的基础上,我们提出了数值扫描的2HDM参数空间,我们调查可用的参数区域和分析模型的约束。从这些结果中,我们定义了一些基准的情况下,捕捉不同方面的非标准希格斯现象,感兴趣的未来大型强子对撞机希格斯搜索。

英文摘要:

We introduce a strategy to study the parameter space of the general, CP-conserving, two-Higgs-doublet Model (2HDM) with a softly broken Z_2-symmetry by means of a new "hybrid" basis. In this basis the input parameters are the measured values of the mass of the observed Standard Model (SM)-like Higgs boson and its coupling strength to vector boson pairs, the mass of the second CP-even Higgs boson, the ratio of neutral Higgs vacuum expectation values, and three additional dimensionless parameters. Using the hybrid basis, we present numerical scans of the 2HDM parameter space where we survey available parameter regions and analyze model constraints. From these results, we define a number of benchmark scenarios that capture different aspects of non-standard Higgs phenomenology that are of interest for future LHC Higgs searches.
