摘要

我们提出了$\texttt{NPointFunctions}$，这是一个包，用于合并$\texttt{FlexibleSUSY}$中任意BSM模型的所需振幅和可观测值。该包依赖与$\texttt{FeynArts}/\texttt{FormCalc}$一起使用的$\texttt{SARAH}$生成的输出，以适当的方式嵌入，从而允许进行单循环级别的计算。由此产生的工具是$\texttt{FlexibleSUSY}$的扩展，这是一个频谱生成器程序的生成器。$\texttt{NPointFunctions}$被设计为可定制，模块化和可扩展的附加过程或振幅依赖的贡献。我们将解释如何实现这些目标，并讨论对默认$\texttt{FlexibleSUSY}$工作流的修改。

NPointFunctions: a calculator of amplitudes and observables in FlexibleSUSY

We present $\texttt{NPointFunctions}$, a package to incorporate desired amplitudes and observables for an arbitrary BSM model in $\texttt{FlexibleSUSY}$. The package relies on the $\texttt{SARAH}$-generated output used with $\texttt{FeynArts}/\texttt{FormCalc}$, embedded in an appropriate way, thus allowing calculations up to one-loop level. The resulting tool is an extension to $\texttt{FlexibleSUSY}$, a generator of spectrum generator programs. $\texttt{NPointFunctions}$ was designed to be customizable, modular and extensible with additional process- or amplitude- dependent contributions. We explain, how these goals are achieved, and discuss modifications to the default $\texttt{FlexibleSUSY}$ workflow.
