 v11 === Description of the model === In the infinite top-quark mass limit, the Higgs field can be effectively coupled with the gluon field via two operators In the infinite top-quark mass limit, the Higgs field can be effectively interacted with the gluon field via [[latex($\mathcal{L}_{\rm eff}=-\frac{1}{4}(C_h \frac{h}{v}-C_{hh}\frac{h^2}{2v^2})G^a_{\mu\nu}G^{a~\mu\nu}$)]] The NLO UFO model based on [[latex($\mathcal{L}_{\rm eff}+\mathcal{L}_{\rm SM}$)]] can be downloaded from [/raw-attachment/wiki/NLOModels/HEFT_DH_UFO.tar.gz here]. The analytical expressions for [[latex($R_2$)]] Feynman rules can be found in appendix B of [https://arxiv.org/abs/1912.13001 arXiv:1912.13001]. === A pedagogical example in MadGraph5_aMC@NLO === In order to handle mixed-order senarios, one has to use the version 3.0.1+ of MadGraph5_aMC@NLO. {{{ > import model HEFT_DH_UFO > generate p p > h h j / t t~ QCD=3 QED=2 NP=2 [QCD] QCD^2<=6 QED^2<=4 NP^2<=4 }}}
