我们提出了一种新的套件，用于研究标准模型之外的模型中的风味可观测值。该设置基于公共代码SARAHandSPheno，并允许轻松实现新的可观察量。有效拉格朗日中相应算子的Wilson系数由SARAH编写的SPheno模块计算。用户还可以通过模块化的方式添加新的算子。为此，开发了一个名为 PreSARAH 的方便的 Mathematica 软件包。它使用 FeynArts 和 FormCalc 在树和 1 循环级别导出通用形状因子，并为 SARAH 生成必要的输入文件。该框架已用于在SARAH中实现BR()、BR()、CR()、BR()、BR()、BR()、BR()、BR()、BR()、BR()、BR()、BR()、、、、BR()、BR()、BR()和BR()。现在可以在各种 SUSY 和非 SUSY 模型中获得对这些可观测值的预测。最后，用户可以使用相同的方法轻松计算其他可观测值。
We present a new kit for the study of flavor observables in models beyond the standard model. The setup is based on the public codesSARAHandSPhenoand allows for an easy implementation of new observables. The Wilson coefficients of the corresponding operators in the effective lagrangian are computed bySPhenomodules written bySARAH. New operators can also be added by the user in a modular way. For this purpose a handyMathematicapackage called thePreSARAHhas been developed. This usesFeynArtsandFormCalcto derive generic form factors at tree- and 1-loop levels and to generate the necessary input files forSARAH. This framework has been used to implement BR(), BR(), CR(), BR(), BR(), BR(), BR(), BR(), BR(), BR(), BR(), BR(),,,, BR(), BR(), BR() and BR() inSARAH. Predictions for these observables can now be obtained in a wide range of SUSY and non-SUSY models. Finally, the user can use the same approach to easily compute additional observables.
