Abstract

We discuss some aspects of the interplay between the top quark and the Higgs boson at the LHC. First we describe what indirect information on the top Yukawa coupling can be extracted from measurements in the Higgs sector. We then show that the study of processes involving $Ht\bar{t}$ and $Hb\bar{b}$ final states can give us information on the spectrum in models of strong electroweak symmetry breaking. In particular, we introduce a novel analysis of the $Hb\bar{b}\to bb\bar{b}\bar{b}$ channel with an excellent discovery potential at the LHC.
