Introducing HiggsBounds 2.0.0
摘要:
我们介绍的计算机程序HiggsBounds的2.0.0版本。该计划测试中性和收费希格斯部门的新模型对目前的排斥界限从LEP和Tevatron。作为输入,它需要选择模型预测,如希格斯质量,分支比,有效耦合和总衰变宽度。然后,该程序使用希格斯搜索的预期和观察到的拓扑截面限制来确定是否在95% C. L.处排除模型的给定参数场景。这些搜索。版本2.0.0包括39/53 LEP/Tevatron Higgs搜索分析,而上一版本(1.2.0)中为13/36。在新纳入的分析中,LEP搜索中性希格斯玻色子玻色子(H)衰变为不可见或强子,LEP搜索通过生产模式(tau+ tau- H)和(b b-bar H),Tevatron搜索通过(t t-bar H),以及LEP和Tevatron搜索带电希格斯玻色子玻色子。此外,在ICHEP'10上展示的所有Tevatron结果均包含在版本2.0.0中。在这次演讲中,我们解释了HiggsBounds实现背后的基本思想,并提供了2.0.0版中实现的搜索拓扑列表。此外,我们应用HiggsBounds 2.0.0(a)确定一个简单的第四代模型的允许的Higgs质量范围,(b)更新/复制MSSM m_h-max基准场景的LEP/Tevatron Higgs排除图,(c)显示Randall-Sundrum模型标量扇区的排除结果。
英文摘要:
We introduce version 2.0.0 of the computer program HiggsBounds. The program tests neutral and charged Higgs sectors of new models against the current exclusion bounds from LEP and the Tevatron. As input, it requires a selection of model predictions, such as Higgs masses, branching ratios, effective couplings and total decay widths. The program then uses the expected and observed topological cross section limits from the Higgs searches to determine whether a given parameter scenario of a model is excluded at the 95% C.L. by those searches. Version 2.0.0 includes 39/53 LEP/Tevatron Higgs search analyses, compared to 13/36 in the previous release (1.2.0). Among the newly included analyses are LEP searches for neutral Higgs bosons (H) decaying invisibly or into hadrons, LEP searches via the production modes (tau+ tau- H) and (b b-bar H), Tevatron searches via (t t-bar H), and LEP and Tevatron searches for charged Higgs bosons. Also, all Tevatron results presented at the ICHEP'10 are included in version 2.0.0. In this talk, we explain the basic ideas behind the implementation of HiggsBounds and provide a list of search topologies implemented in version 2.0.0. Furthermore, we apply HiggsBounds 2.0.0 to (a) determine the allowed Higgs mass range for a simple 4th generation model, (b) update/reproduce LEP/Tevatron Higgs exclusion plots for the MSSM m_h-max benchmark scenario, and (c) show exclusion results for the scalar sector of the Randall-Sundrum model.
