Boosted Higgs Channels

Abstract

In gluon fusion both a modified top Yukawa and new colored particles can alter the cross section. However in a large set of composite Higgs models and in realistic areas of the MSSM parameter space, these two effects can conspire and hide new physics in a Standard Model-like inclusive cross section. We first show that it is possible to break this degeneracy in the couplings by demanding a boosted Higgs recoiling against a high-$p_T$ jet. Subsequently we propose an analysis based on this idea in the $H\to 2\ell +E{/}_T$ channels. This measurement allows an alternative determination of the important top Yukawa besides the $t\bar{t}H$ channel.
