我们描述了Fortran代码CPsuperH2.0，它包含了对其前身CPsuperH的几个改进和扩展。它实现了对希格斯-玻色子极质量的改进计算，特别是对4×4中性希格斯传播子矩阵（包括Goldstone玻色子）的全面处理，以及对自能和汤川耦合中的阈值效应的更完整处理，改进了对两体希格斯衰变的处理，一些重要的三体衰变，以及希格斯介导的双环对电偶极矩的贡献。CPsuperH2.0还实现了对几个B介子观测值的综合处理，包括B→μ+μ−，Bd→τ+τ−,Bu→τν， B→Xsγ和后者的违反cp的不对称ACP的分支比，以及对B，d0−B¯s，d0质量差的超对称贡献。这些新增功能使CPsuperH2.0成为一个有吸引力的集成工具，用于分析超对称CP和风味物理，以及在高能对撞机（如Tevatron， LHC和线性对撞机）上搜索新物理。项目摘要：项目名称：CPsuperH2.0目录标识符：ADSR_v2_0项目摘要URL:http://cpc.cs.qub.ac.uk/summaries/ADSR_v2_0.html项目可从：爱尔兰贝尔法斯特女王大学CPC项目图书馆获得许可条款：标准CPC许可，http://cpc.cs.qub.ac.uk/licence/licence.html号。分布式程序的行数，包括测试数据等：13 290分布式程序字节数，包括测试数据等：89 540发布格式：tar.gz编程语言：Fortran 77计算机：Linux操作系统：Linux内存：32mb分类：11.1前版本目录标识：ADSR_v1_0前版本日志参考号：CPC 156(2004) 283新版本是否取代前版本？问题性质：改进了具有显式CP违和的最小超对称标准模型中中性和带电希格斯玻色子的质谱、衰变宽度和分支比的计算。该程序基于最近的重正化群改进图表计算，包括主要的高阶对数和阈值修正，b-夸克汤川耦合恢复效应和改进的希格斯-玻色子极质量移动处理。计算了希格斯玻色子与标准模型规范玻色子和费米子的耦合、与它们的超对称伙伴的耦合以及所有的三线性和四次希格斯玻色子自耦合。新的实现包括对4×4（2×2）中性（带电）希格斯传播子矩阵的全面处理，以及依赖于质心的希格斯-玻色子与胶子和光子的耦合，对电偶极矩的双环希格斯介导的贡献，以及对几个b介子可观测值的综合处理。求解方法：几种希格斯衰变模式的一维数值积分，阈值修正和希格斯-玻色子极质量的迭代处理，以及中性微子质量矩阵的数值对角化。新版本的原因：主要是提供一个连贯的数值框架，计算一致的低和高能实验的观测值。修订摘要：改进了对希格斯玻色子质量和传播子的处理。改进了希格斯-玻色子耦合和衰变的处理。希格斯介导的双环电偶极矩。b介子可见。运行时间：小于0.1秒。
We describe the Fortran code CPsuperH2.0, which contains several improvements and extensions of its predecessor CPsuperH. It implements improved calculations of the Higgs-boson pole masses, notably a full treatment of the 4×4 neutral Higgs propagator matrix including the Goldstone boson and a more complete treatment of threshold effects in self-energies and Yukawa couplings, improved treatments of two-body Higgs decays, some important three-body decays, and two-loop Higgs-mediated contributions to electric dipole moments. CPsuperH2.0 also implements an integrated treatment of several B-meson observables, including the branching ratios of Bs→μ+μ−, Bd→τ+τ−, Bu→τν, B→Xsγ and the latter's CP-violating asymmetry ACP, and the supersymmetric contributions to the Bs,d0−B¯s,d0mass differences. These additions make CPsuperH2.0 an attractive integrated tool for analyzing supersymmetric CP and flavour physics as well as searches for new physics at high-energy colliders such as the Tevatron, LHC and linear colliders.1PROGRAM SUMMARY: Program title: CPsuperH2.0 Catalogue identifier: ADSR_v2_0 Program summary URL:http://cpc.cs.qub.ac.uk/summaries/ADSR_v2_0.html Program obtainable from: CPC Program Library, Queen's University, Belfast, N. Ireland Licensing provisions: Standard CPC licence, http://cpc.cs.qub.ac.uk/licence/licence.html No. of lines in distributed program, including test data, etc.: 13 290 No. of bytes in distributed program, including test data, etc.: 89 540 Distribution format: tar.gz Programming language: Fortran 77 Computer: PC running under Linux and computers in Unix environment Operating system: Linux RAM: 32 Mbytes Classification: 11.1 Catalogue identifier of the previous version: ADSR_v1_0 Journal reference of the previous version: CPC 156 (2004) 283 Does the new version supersede the previous version?: Yes Nature of problem: The calculations of mass spectrum, decay widths and branching ratios of the neutral and charged Higgs bosons in the Minimal Supersymmetric Standard Model with explicit CP violation have been improved. The program is based on recent renormalization-group-improved diagrammatic calculations that include dominant higher-order logarithmic and threshold corrections, b-quark Yukawa-coupling resummation effects and improved treatment of Higgs-boson pole-mass shifts. The couplings of the Higgs bosons to the Standard Model gauge bosons and fermions, to their supersymmetric partners and all the trilinear and quartic Higgs-boson self-couplings are also calculated. The new implementations include a full treatment of the 4×4(2×2) neutral (charged) Higgs propagator matrix together with the center-of-mass dependent Higgs-boson couplings to gluons and photons, two-loop Higgs-mediated contributions to electric dipole moments, and an integrated treatment of several B-meson observables. Solution method: One-dimensional numerical integration for several Higgs-decay modes, iterative treatment of the threshold corrections and Higgs-boson pole masses, and the numerical diagonalization of the neutralino mass matrix. Reasons for new version: Mainly to provide a coherent numerical framework which calculates consistently observables for both low- and high-energy experiments. Summary of revisions: Improved treatment of Higgs-boson masses and propagators. Improved treatment of Higgs-boson couplings and decays. Higgs-mediated two-loop electric dipole moments. B-meson observables. Running time: Less than 0.1 seconds.
