Description

We introduce a new approach to study jet substructure in the center-of-mass frame of the jet. We demonstrate that it can be used to discriminate the boosted heavy particles from the QCD jets and the method is complimentary to the existing other jet substructure algorithms. Applications to searches for hadronically decaying W/Z+jets, top jet and heavy resonance that decays to final states with W/Z and top jets are also discussed. The talk is based on my papers published in Physical Review D (PRD85,034007 (2012) & PRD 87, 074007 (2013)) and some recent work afterwards (to be submitted to a paper).
