Search for the elusive Higgs boson using jet structure at LHC

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. with mass of few GeV which sequently decay into four gluons, i.e. h -> 2 chi -> 4g. Since. 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. decay in the detector chi By using electromagnetic calorimeter-based and jet substructure analyses, we show in two cases of different chi masses that it is quite promising to extract the signal of Higgs boson out of large QCD background.
