Rest frame subjet algorithm with SISCone jet for fully hadronic decaying Higgs search

The rest frame subjet algorithm is introduced to define the subjets for the SISCone jet; with this algorithm, an infrared and collinear safe jet shape observable N-subjettiness τNʲ is defined to discriminate the fat jet, from a highly boosted color singlet particle decaying to N partons, from the QCD jet. Using rest frame subjets and τ₂ʲ on dijets from highly boosted $H/W/Z$ bosons through pp→HW,HZ with mH=120 GeV, we found that the statistical significance of the signal, from the fully hadronic channels, is about 2σ for 14 TeV collisions with L~30 fb^-1.
