Higgs Production In Association with Two Jets at The LHC

The Higgs boson is a keystone of the mechanism of Electroweak Symmetry Breaking (EWSB) in the Standard Model of particles. Besides the Higgs boson discovery, which will be widely pursued at the Large Hadron Collider (LHC) at CERN, in order to analyse EWSB it will be crucial to study the Higgs couplings. A key component of the programme to measure the couplings, and in particular the ones of the Higgs to the W- or Z-bosons, will be the vector-boson fusion (VBF) process, characterised by the production of a Higgs boson plus two jets. However, Higgs + 2-jet production occurs mostly via gluon fusion, which, while part of the Higgs signal, constitutes a background when trying to isolate the gauge couplings of the VBF process. We give an overview of Higgs production, and analyse some distributions, in particular the azimuthal correlation between the jets, which may distinguish the VBF process from gluon fusion. (author)
