摘要

我们提出了在标准模型有效理论(SMEFT)中对胶子融合中希格斯玻色子对产生的NLO(双环)QCD修正，包括平方维6算子和双插入算子。截断EFT展开的不同选择与非线性EFT方法(HEFT)进行了对比，并通过几个现象学例子说明了它们的效果。

Beyond dimension six in SM Effective Field Theory: a case study in Higgs pair production at NLO QCD

We present the NLO (two-loop) QCD corrections to Higgs boson pair production in gluon fusion within Standard Model Effective Theory (SMEFT), including also squared dimension-6 operators and double insertions of operators. The different options to truncate the EFT expansion are contrasted to a non-linear EFT approach (HEFT) and their effects are illustrated by several phenomenological examples.
