我们描述了SuperIso v2.3，这是一个用于在标准模型(MSSM)的最小超对称扩展(MSSM)中评估风味物理观察值的公共程序。SuperIso v2.3除了第一版的主要目的是B→K∗γ的同位旋不对称性外，还增加了新的风味观测，如BS→μ+μ−的分支率、B→τντ的分支率、B→Dτντ的分支率和K→μνμ的分支率。在这个版本中，B→Xsγ的分支比的计算也得到了改进，因为它现在除了包括部分NLO超对称贡献外，还包括了NNLO标准模型贡献。该程序还计算了Muon反常磁矩(g−2)。该套装包括四个样本型号，即mSUGRA、NUHM、AMSB和GMSB。SuperIso使用SUSY Les Houches Accord文件(SLHA1或SLHA2)作为输入，该文件可以由程序通过调用外部频谱计算器自动生成，也可以由用户提供。可观测值的计算在附录中有详细说明，其中还提供了每个可观测值的允许间隔的建议。计划摘要：计划标题：SuperISO目录识别符：AEAN_V2_0计划摘要URL:http://cpc.cs.qub.ac.uk/summaries/AEAN_v2_0.html计划可从：CPC计划图书馆，女王大学，贝尔法斯特，北爱尔兰许可条款：GNU通用公共许可证号。分布式程序中的行数，包括测试数据等：5977号分布式程序中的字节数，包括测试数据等：39 375分布格式：tar.gz编程语言：C(符合C99标准)计算机：32位或位PC，Mac操作系统：LINUX，MacOS RAM：小于1Mb分类：11.6先前版本的目录标识：AEAN_v1_0先前版本的日志参考：COMPUT。太棒了。通讯。178(2008)745外部例程：ISASUGRA/ISAJET和/或SOFTSUSY新版本是否取代了以前的版本？：是的问题的性质：在最小的味道破坏的最小超对称标准模型中，计算风味物理观测数据以及Muon反常磁矩，以便导出对超对称参数空间的约束。解决方法：SuperIso使用SUSY Les Houches Accord文件，该文件可以通过调用SOFTSUSY或ISAJET自动生成，也可以由用户提供。该文件包含超对称粒子的质量和耦合。然后，SuperIso计算出最受约束的味道物理可观测值和介子(g−2)。SuperIso能够在不同的超对称破缺情况下执行计算，如mSUGRA、NUHM、AMSB和GMSB。新版本的原因：这个新版本加入了几个额外的观测数据的计算，b→Sγ的包含分枝比现在是以标准模型的NNLO精度计算的。因此，实现的例程被广泛修改。修订摘要：不同寻常的特点：代码非常模块化，可以很容易地添加计算新观测数据的新例程。运行时间：不到1秒
We describe SuperIso v2.3 which is a public program for evaluation of flavor physics observables in the minimal supersymmetric extension of the Standard Model (MSSM). SuperIso v2.3, in addition to the isospin asymmetry of B→K∗γ, which was the main purpose of the first version, incorporates new flavor observables such as the branching ratio of Bs→μ+μ−, the branching ratio of B→τντ, the branching ratio of B→Dτντand the branching ratio of K→μνμ. The calculation of the branching ratio of B→Xsγ is also improved in this version, as it now includes NNLO Standard Model contributions in addition to partial NLO supersymmetric contributions. The program also computes the muon anomalous magnetic moment (g−2). Four sample models are included in the package, namely mSUGRA, NUHM, AMSB and GMSB. SuperIso uses a SUSY Les Houches Accord file (SLHA1 or SLHA2) as input, which can be either generated automatically by the program via a call to external spectrum calculators, or provided by the user. The calculation of the observables is detailed in the Appendices, where a suggestion for the allowed intervals for each observable is also provided.

Phys. Comm. 178 (2008) 745 External routines: ISASUGRA/ISAJET and/or SOFTSUSY Does the new version supersede the previous version?: yes Nature of problem: Calculation of flavor physics observables as well as the muon anomalous magnetic moment in the Minimal Supersymmetric Standard Model with minimal flavor violation, in order to derive constraints on the supersymmetric parameter space. Solution method: SuperIso uses a SUSY Les Houches Accord file, which can be either generated automatically via a call to SOFTSUSY or ISAJET, or provided by the user. This file contains the masses and couplings of the supersymmetric particles. SuperIso then computes the most constraining flavor physics observables and the muon (g−2). SuperIso is able to perform the calculations in different supersymmetry breaking scenarios, such as mSUGRA, NUHM, AMSB and GMSB. Reasons for new version: This new version incorporates the calculation of several additional observables, and the inclusive branching ratio of b→sγ is now computed at NNLO accuracy for the Standard Model. The implemented routines are therefore extensively modified. Summary of revisions: Unusual features: The code is very modular, and new routines for calculating new observables can be easily added.
