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

$\mathcal{L}_{\rm eff}=-\frac{1}{4}(C_h \frac{h}{v}-C_{hh}\frac{h^2}{2v^2})G^a_{\mu\nu}G^{a~\mu\nu}$

where $G^a_{\mu\nu}$ is the gluon field strength tensor.

The NLO UFO model based on $\mathcal{L}_{\rm eff}+\mathcal{L}_{\rm SM}$ can be downloaded from here.
