Higgs Boson with Large Bottom Yukawa Coupling at Tevatron and LHC

We study the discovery reach of the Tevatron and the LHC for detecting a Higgs boson predicted in composite models of the electroweak symmetry breaking or in supersymmetric theories, with an enhanced b-quark Yukawa coupling via $p \bar{p} / p p \to b\bar{b} h (\to b\bbar)+X$. Our analysis shows that studying this process at the Tevatron Run II or the LHC can provide strong constraints on these models.
