New approach to identifying boosted hadronically decaying particles using jet substructure in its center-of-mass frame

In this paper, 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 complementary to other jet substructure algorithms. Applications to searches for hadronically decaying W/Z + jets and heavy resonances that decay to a WW final state are also discussed.
