The abstract, sentence by sentence

arXiv listing abstract v2. Results and the main claim are underlined; show every role.

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 $\chi$ with mass of few GeV which sequently decay into four gluons, i.e. $h\to 2\chi \to 4g$. Since $\chi$ 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 $\chi$ decay in the detector. 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.

Original 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 $\chi$ with mass of few GeV which sequently decay into four gluons, i.e. $h\to 2\chi \to 4g$. Since $\chi$ 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 $\chi$ decay in the detector. 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.

Soft Drop

Soft drop generalizes the modified mass-drop tagger with an angular exponent beta, and its beta = 0 energy-loss spectrum is Sudakov safe and largely independent of the strong coupling.
Energy Correlation Functions for Jet Substructure
hep-ph 2013-04 accept novelty 7.0 of 10

Ratios of generalized energy correlation functions tag N-prong jet substructure without subjet finding, and the two-point ratio separates quark from gluon jets better than jet angularities at small angular exponent.
Identifying Boosted Objects with N-subjettiness
hep-ph 2010-11 accept novelty 7.0 of 10

A new jet shape, the ratio of 2-subjettiness to 1-subjettiness (and 3-to-2 for tops), separates boosted W bosons and top quarks from QCD jets at roughly 30% signal efficiency for a 1% fake rate in Pythia simulation.
Jet Substructure Without Trees

A pairwise, pT-weighted angular correlation function, differentiated in log R, exposes subjet angular and mass scales directly from jet constituents and yields a competitive boosted-top tagger.
Stop Reconstruction with Tagged Tops
hep-ph 2010-06 conditional novelty 6.0 of 10

A hadronic top tagger makes stop pair production visible in the all-hadronic plus missing-energy channel at the LHC, where the semi-leptonic channel fails.
