Fusion

The hint of a new particle around 125 GeV at the LHC through the decay modes of diphoton and a number of others may point to quite a number of possibilities. While at the LHC the dominant production mechanism in the standard model is via the gluon fusion process, the alternative vector boson fusion is more sensitive to electroweak symmetry breaking through the $WWh$ and $ZZh$ couplings and therefore can be used to probe for models beyond the standard model. In this work, using the well known dijet-tagging technique to single out the vector boson fusion mechanism, we investigate its capability to discriminate a number of models, including the standard model Higgs boson, fermiophobic Higgs boson, Randall-Sundrum radion, inert-doublet-Higgs model, two-Higgs-doublet model, and selective benchmark points of MSSM and NMSSM.
