Abstract
Possible extensions of the Standard Model predict modifications of the Higgs couplings to gluons and to the SM top quark. The values of these two couplings can, in general, be independent. We discuss a way to measure these interactions by studying the Higgs production at high p T within an effective field theory formalism. We also propose an observable r ± with reduced theoretical errors and suggest its experimental interpretation.
