  We present a detailed phenomenological analysis of the production of a
Standard Model Higgs boson in association with up to three jets. The Higgs is
produced via gluon fusion, which is an irreducible background to the vector
boson fusion mechanism. We calculate the next-to-leading order corrections in
QCD in the limit of an infinitely heavy top quark. Numerical results are
presented for a large variety of observables, for different selection cuts, and
for different choices of the jet tagging scheme.
