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, 2HDME）是一款C++程序，可针对一般形式且可能存在CP破坏（CP-violating）的2希格斯二重态模型（2 Higgs Doublet Model），以两圈阶快速完成重整化群方程（renormalization group equation）跑动演化计算。该程序内置多项核心功能：简易树级（tree-level）质量计算、斜参数（oblique parameters）S、T与U的求解、标量势（scalar potential）的多种参数化形式，以及对标量势的微扰性（perturbativity）、幺正性（unitarity）与树级稳定性（tree-level stability）的检验。本文简要介绍了2HDME的程序架构，演示了其使用方法，并列举了部分最常用的功能函数。
