Higgs Production

 The dominating Higgs production mechanism at the LHC will be the gluon fusion process for all possible Higgs masses. Other processes with their Feynman diagrams in fig. 2.1 are also of interest because of the special signatures they can provide for the identification of the Higgs. In fig. 2.2 the cross section is shown as a function of the standard model Higgs mass. At the highest masses a significant part of the cross section is from vector boson fusion.
