An exactly solvable large N model is constructed which reduces at low energies to the Standard Model plus the dimension six Higgs-gauge operators g12 H^† H Bμν Bμν, g22 H^† H Waμν Waμν, g1 g2 H^† τa H Waμν Bμν, and εabc WaμνWbνρWcρμ. All other dimension six operators are suppressed by powers of 1/N. The Higgs-gauge operators lead to deviations from the Standard Model h → γγ and h → γZ rates. A simple variant of the model can be used to also generate the Higgs-gluon operator g32 H^† H GAμν GAμν which contributes to the Higgs production rate via gluon fusion.
