论文摘要
我们介绍了Higgs玻色子对在Gluon融合中的实施，该过程中包含五个异常耦合的非线性有效现场理论框架。 POWHEG-BOX-V2中可用的代码包括带有大量顶级夸克的完整NLO QCD校正。所有五个耦合都可以由用户修改。我们在NLO $ M_ {HH} $ Shape Analysis提供的七个基准点上显示$ m_ {hh} $发行，并淋浴$ p_t^{hh} $分布，该界面由接口到Pythia-8和Herwig-7.2。
We present the implementation of Higgs boson pair production in gluon fusion within a non-linear Effective Field Theory framework containing five anomalous couplings for this process. The code, available within the POWHEG-BOX-V2, includes full NLO QCD corrections with massive top quarks. All five couplings can be modified by the user. We show $m_{hh}$ distributions at seven benchmark points provided by an $m_{hh}$ shape analysis at NLO and showered $p_T^{hh}$ distributions resulting from an interface to Pythia-8 and Herwig-7.2.
