The next-to-leading order (NLO) cross section of the gluon fusion process is matched to parton showers in the MC@NLO approach. We work in the framework of MadGraph5_aMC@NLO and document the inclusion of the full quark-mass dependence in the Standard Model (SM) as well as the state-of-the-art squark and gluino effects within the Minimal Supersymmetric SM embodied in the program SusHi. The combination of the two programs is realized by a script which is publicly available and whose usage is detailed. We discuss the input cards and the relevant parameter switches. One of our focuses is on the shower scale which is specifically important for gluon-induced Higgs production, particularly in models with enhanced Higgs-bottom Yukawa coupling.
胶子融合过程的次领头阶（NLO）截面在MC@NLO方法中与部分子淋浴进行匹配。我们在MadGraph5_aMC@NLO框架内开展工作，并记录了标准模型（SM）中完整的夸克质量依赖性以及程序SusHi中体现的最小超对称标准模型内最先进的 squark 和胶微子效应。这两个程序的结合通过一个公开可用的脚本实现，其使用方法有详细说明。我们讨论了输入卡和相关的参数开关。我们的重点之一是淋浴标度，它对于胶子诱导的希格斯玻色子产生特别重要，尤其是在具有增强的希格斯 - 底夸克汤川耦合的模型中。
