    26 In the infinite top-quark mass limit, the Higgs field can be effectively coupled with the gluon field via two operators
     26In the infinite top-quark mass limit, the Higgs field can be effectively interacted with the gluon field via

     38In order to handle mixed-order senarios, one has to use the version 3.0.1+ of MadGraph5_aMC@NLO.
