Associated Higgs production with bottom quarks at hadron colliders

Higgs-boson production in association with bottom quarks, p (p) over bar /pp --> b (b) over barH+X, is an important discovery channel for supersymmetric Higgs particles at the Tevatron and the LHC. We present higher-order QCD predictions for inclusive cross sections and for the production of a Higgs boson in association with high-p(T) bottom quarks. We compare calculations performed in a four-flavour scheme based on the parton processes gg, q (q) over bar --> b (b) over barH with five-flavour scheme calculations based on bottom-quark scattering.
