论文摘要
GM2CALC是用于计算最小超对称标准模型中$A_μ$的精确贡献的领先工具。在此程序中，我们详细介绍了GM2CALC版本2的扩展，因此它可以根据参考文献中的工作计算两循环的两循环Doublet模型（2HDM）中的两环贡献。 [1]。 2HDM是一个简单的模型，但它是标准模型的少数单场扩展之一，能够解释MUON $ G-2 $异常。我们演示了GM2CALC2功能强大且灵活的2HDM功能，其中包括文献中最精确的贡献，并允许用户以其最喜欢的2HDM类型以及使用复杂且违反Lepton风味的耦合。 GM2CALC2具有多个接口和输入灵活性，既是独立代码，也是较大代码工具链的一部分。
GM2Calc is a leading tool for calculating precise contributions to $a_μ$ in the Minimal Supersymmetric Standard Model. In this proceeding we detail GM2Calc version 2 where it is extended so it can calculate two-loop contributions to $a_μ$ in the Two-Higgs Doublet Model (2HDM), based on the work in Ref. [1]. The 2HDM is a simple model, yet it is one of the few single field extensions of the Standard Model which is able to explain the muon $g-2$ anomaly. We demonstrate the powerful and flexible 2HDM capabilities of GM2Calc2, which include the most precise contributions in the literature and allow the user to work in their favourite type of the 2HDM as well as use complex and lepton flavour violating couplings. With its multiple interfaces and input flexibility, GM2Calc2 is a powerful tool both as a standalone code and as part of a larger code toolchain.
