 v9 == An effective theory for single Higgs and double Higgs production == == The effective theory for single Higgs and double Higgs production == === Authors === In the infinite top-quark mass limit, the Higgs field can be effectively coupled with the gluon field via two operators [[latex($L_{eff}=\frac{1}{4}*(C_h \frac{h}{v}-C_{hh}\frac{h^2}{v^2})GG$)]] [[latex($L_{eff}=-\frac{1}{4}(C_h \frac{h}{v}-C_{hh}\frac{h^2}{2v^2})G^a_{\mu\nu}G^{a~\mu\nu}$)]] where G is the gluon field strength tensor. where [[latex($G^a_{\mu\nu}$)]] is the gluon field strength tensor.
