Abstract: Precise measurements of the Higgs couplings are crucial to pin down new physics beyond the StandardModel. In gluon fusion, both a modified top Yukawa and new colored particles can alter the crosssection. However, in a large set of composite Higgs models and in realistic areas of the MSSMparameter space, these two effects can conspire and hide new physics in a Standard Model likeinclusive cross section.We show that it is possible to break this degeneracy in the couplings by demanding a boosted Higgsrecoiling against a high-$p_T$ jet. We propose an analysis based on this idea in the $H\to2\ell+{\bfp}\!\!\!/_T$ channel. This measurement allows for an alternative determination of the important topYukawa besides the $t\bar t H$ channel.
