H-COUP: A program for one-loop corrected Higgs boson couplings in non-minimal Higgs sectors

We describe a numerical calculation tool H-COUP written in Fortran, which provides one-loop electroweak corrected vertices for the discovered Higgs boson h(125) in various Higgs sectors. The renormalization is based on the improved on-shell scheme without gauge dependence. In the first version H-COUP_1.0, the following models are included, namely, the Higgs singlet model, four types (Type-I, Type-II, Type-X, Type-Y) of two Higgs doublet models with a softly-broken Z_2 symmetry and the inert doublet model. We first briefly introduce these models and then explain how to install and run this tool in an individual machine. A sample of numerical outputs is provided for user information.本文介绍一款采用Fortran语言编写的数值计算工具H-COUP，该工具可为各类希格斯扇区中已发现的希格斯玻色子h(125)提供单圈电弱修正顶点。其重整化方案基于无规范依赖性的改进在壳方案（improved on-shell scheme）。在首个版本H-COUP_1.0中，该工具涵盖以下模型：希格斯单态模型、四类（I型、II型、X型、Y型）带有软破缺Z₂对称性的双希格斯二重态模型，以及惰性二重态模型。本文首先对上述模型进行简要介绍，随后详细说明如何在单机环境下安装并运行该工具，同时提供数值输出示例以供用户参考。
