我概述了 Mathematica 包 SARAH 提供的用于研究新模型的功能。一般来说，SARAH 可以处理 MSSM 之外的各种模型，并带有额外的手性超场、额外的规范组或狄拉克高吉诺质量等独特特征。所有这些模型都可以在 SARAH 中以紧凑的形式实现，并且易于使用：SARAH 提取给定模型的所有分析属性，如二环重整化群方程、蝌蚪方程、质量矩阵和顶点。还可以获得对蝌蚪和自能的一环和二环校正。对于数值计算，SARAH 可以与其他工具连接来获取质谱、检查风味或暗物质约束、测试真空稳定性或进行对撞机研究。特别是，通过结合重要的双环校正，SPheno 的接口允许在给定模型中精确预测希格斯质量，其精度可与 MSSM 精度相当。我通过 B-L-SSM 的示例详细展示了 SARAH 如何与 SPheno、HiggsBounds/HiggsSignals、FlavorKit、Vevacious、CalcHep、MicrOmegas、WHIZARD 和 MadGraph 一起用于研究模型的所有现象学方面。
I give an overview about the features the Mathematica package SARAH provides to study new models. In general, SARAH can handle a wide range of models beyond the MSSM coming with additional chiral superfields, extra gauge groups, or distinctive features like Dirac gaugino masses. All of these models can be implemented in a compact form in SARAH and are easy to use: SARAH extracts all analytical properties of the given model like two-loop renormalization group equations, tadpole equations, mass matrices, and vertices. Also one- and two-loop corrections to tadpoles and self-energies can be obtained. For numerical calculations SARAH can be interfaced with other tools to get the mass spectrum, to check flavour or dark matter constraints, and to test the vacuum stability or to perform collider studies. In particular, the interface to SPheno allows a precise prediction of the Higgs mass in a given model comparable to MSSM precision by incorporating the important two-loop corrections. I show in great detail with the example of the B-L-SSM how SARAH together with SPheno, HiggsBounds/HiggsSignals, FlavorKit, Vevacious, CalcHep, MicrOmegas, WHIZARD, and MadGraph can be used to study all phenomenological aspects of a model.
