摘要
HiggsBounds是欧洲科学家开发的高能物理程序包。它利用LEP、Tevatron和LHC寻找Higgs粒子的实验结果,讨论当前实验对Higgs物理的限制。HiggsBounds的代码和使用说明书可以从如下网址得到: www.ippp.dur.ac.uk/HiggsBounds
程序HiggsBounds有三种版本:命令行版本,子程序版本和在线版本,其各自的特点和要求在第二章节中有详细介绍。简单来说,用户根据HiggsBounds的使用说明,把待研究模型的理论预言作为输入信息提供给程序HiggsBounds,程序就能判断在已有的实验限制下,用户提供信息所对应的参数点是否被排除(95%C.L.),并且告诉用户哪个道最敏感。在高能粒子物理实验高速发展的今天,HiggsBounds使理论预言与实验寻找Higgs粒子数据直接比较成为可能,因此学习HiggsBounds,使之为我所用也就显得十分有意义。现在,HiggsBounds有Fortran 77和Fortran 90两种代码形式。其代码版本也在不断更新完善中,本论文是在HiggsBounds-1.1.0基础上展开的。
HiggsBounds is a computer code that tests theoretical predictions of models with arbitrary Higgs sectors against the exclusion bounds obtained from the Higgs searches at LEP, the Tevatron and LHC. The included experimental information comprises exclusion bounds at 95% C.L. on topological cross sections. In order to determine which search topology has the highest exclusion power, the program also includes for each topology information from the experiments on the expected exclusion bound, which would have been observed in case of a pure background distribution. Using the predictions of the desired model provided by the user as input, HiggsBounds determines the most sensitive channel and tests whether the considered parameter point is excluded at the 95% C.L. The code has both a Fortran 77 and Fortran 90 version. The code can be invoked as a command line version, a subroutine version and an online version. It can be operated in a command line mode that can process input files in a variety of formats, as a subroutine suitable for inclusion in user applications, and as an online version, available at the URL: http://www.ippp.dur.ac.uk/HiggsBounds.
