2HDME: Two-Higgs-Doublet Model Evolver

Two-Higgs-Doublet Model Evolver (2HDME) is a C++ program that provides the functionality to perform fast renormalization group equation running of the general, potentially CP-violating, 2 Higgs Doublet Model at 2-loop order. Simple tree-level calculations of masses; calculations of the oblique parameters S, T and U; different parameterizations of the scalar potential; tests of perturbativity, unitarity and tree-level stability of the scalar potential are also implemented. We briefly describe the 2HDME’s structure, provide a demonstration of how to use it and list some of the most useful functions.双希格斯二重态模型演化程序（Two-Higgs-Doublet Model Evolver，简称2HDME）是一款C++程序，可针对通用且可能存在CP破坏的双希格斯二重态模型实现两圈阶重整化群方程的快速跑动计算。该程序还集成了多项核心功能：质量的简单树级计算、斜参数S、T、U的计算、标量势的多种参数化形式，以及标量势的微扰性、幺正性与树级稳定性检验等。本文简要介绍了2HDME的程序架构，演示了其使用方法，并列出了部分最常用的实用函数。
