Contribution
It offers the first detailed NLO QCD calculations for Higgs plus multi-jet production in gluon fusion, considering various jet tagging schemes and selection cuts.
Findings
NLO corrections significantly affect cross sections and distributions.
Results help distinguish gluon fusion from vector boson fusion.
Provides benchmarks for experimental analyses.
Abstract
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.
