Abstract

We consider the production of a light non-standard model Higgs boson of order 100 GeV with an associated W boson at CERN Large Hadron Collider. We focus on an interesting scenario that, the Higgs boson decays predominately into two light scalars χ with mass of few GeV which sequently decay into four gluons, i.e. h → 2χ → 4g. Since χ is much lighter than the Higgs boson, it will be highly boosted and its decay products, the two gluons, will move close to each other, resulting in a single jet for χ decay in the detector. By using electromagnetic calorimeter-based and jet substructure analyses, we show in two cases of different χ masses that it is quite promising to extract the signal of Higgs boson out of large QCD background.
