Higgs Boson Production with Bottom Quarks at Hadron Colliders

Abstract

One of the most pressing issues at current and future hadron collider experiments is the discovery of one (or more) Higgs bosons. The Standard Model (SM) predicts a single Higgs boson whose couplings to fermions are proportional to the mass of the fermion, hence the production of the Higgs boson with light quarks (e.g. bottom quarks) is suppressed compared to other production channels involving top quarks or heavy gauge bosons. However, in some extensions of the SM (such as the Minimal Supersymmetric Standard Model, or MSSM), the Yukawa couplings for b quarks can become strongly enhanced. In this scenario, the production of a Higgs boson with bb̄ can dominate over other production channels and could provide a unique opportunity to directly probe the b quark Yukawa coupling. The theoretical prediction of bb̄h production at hadron colliders involves several subtle issues and depends on the number of b quarks identified, or tagged, in the final state. Potentially large logarithms arise from the integration over the phase space of the final state b quarks. These large logarithms appear at all orders in perturbation theory and could spoil the convergence of the perturbative expansion of
