本文提出了H-COUP_ver 2的概念，它计算了质量为125 GeV的Higgs玻色子在各种扩展Higgs模型中的衰变率（包括高阶修正）。在以前的版本（H-COUP_1. 0），只有一个完整的希格斯玻色子顶点集在单圈水平上的规范不变的方式在这些模型中进行评估。H-COUP_ver 2包含H-COUP_1的所有功能。0.在简要介绍了这些扩展的希格斯模型，并讨论了它们的理论和实验限制，我们总结了重整化顶点和衰变率的公式。然后，我们将通过一些数值示例解释如何安装和运行H-COUP_ver 2。程序摘要程序标题：H-COUP版本2 CPC程序文件库链接：http：//dx。doi。org/10.17632/f88szmrj5x。2开发人员的存储库链接：http：//www-het。物理科学大坂U。AC. jp/hcoup/许可条款：GPL v3编程语言：Fortran 90以前版本的期刊参考：Comput.物理通讯233（2018），134-144新版本是否取代以前的版本？：是新版本的原因：以前的版本（H-COUP_1. 0），它数值计算了质量为125 GeV的希格斯玻色子的全套单圈校正顶点函数，并没有自动提供衰变率，总衰变宽度和分支比。此外，QCD修正没有包括在以前的版本。修订摘要：作为输出，加入了具有NLO电弱和NNLO QCD修正的希格斯玻色子的衰变分支比和总衰变宽度。问题性质：在Higgs单重态模型、具有Z2对称性软破缺的四种类型（Type-I、Type-II、Type-X、Type-Y）双重态模型和惰性双重态模型中，在电弱NLO和QCD NNLO条件下，数值计算了Higgs玻色子的衰变率和总衰变宽度.方法的求解：分别用改进的在壳层方案和MS ′方案计算了衰变率的电弱修正和QCD修正。其他评论，包括限制和不寻常的功能：上一版本的所有功能均包含在H-COUP_ver 2中。参考文献：[1] S.

We present the concept of H-COUP_ver 2, which evaluates the decay rates (including higher order corrections) for the Higgs boson with a mass of 125GeV in various extended Higgs models. In the previous version (H-COUP_1. 0), only a full set of the Higgs boson vertices are evaluated at one-loop level in a gauge invariant manner in these models. H-COUP_ver 2 contains all the functions of H-COUP_1. 0. After shortly introducing these extended Higgs models and discussing their theoretical and experimental constraints, we summarize formulae for the renormalized vertices and the decay rates. We then explain how to install and run H-COUP_ver 2 with some numerical examples.

Phys. Commun. 233 (2018), 134–144 Does the new version supersede the previous version?: Yes Reasons for the new version: The previous version (H-COUP_1. 0), which numerically evaluates the full set of one-loop corrected vertex functions for the Higgs boson with a mass of 125 GeV, does not automatically provide the decay rates, the total decay width and branching ratios. In addition, QCD corrections have not been included in the previous version. Summary of revisions: Decay branching ratios and the total decay width for the Higgs boson with NLO electroweak and NNLO QCD corrections are added as outputs. Nature of problem: Decay rates for the Higgs boson and the total decay width are numerically evaluated at NLO for electroweak and NNLO for QCD in 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. Solution of method: Electroweak and QCD corrections to the decay rates are computed by the improved on-shell scheme and the MS¯ scheme, respectively. Additional comments including restrictions and unusual features: All functions of the previous version are included in H-COUP_ver 2. References:[1] S. Kanemura, M. Kikuchi, K. Sakurai, K.
