Identifying boosted hadronically decaying top quark using jet substructure in its center-of-mass frame
arXiv:1303.3521 · doi:10.1103/PhysRevD.87.074007
Abstract
In this paper we study the identification of boosted hadronically decaying top quarks using jet substructure in the center-of-mass frame of the jet. We demonstrate that the method can greatly reduce the QCD jet background while maintaining high identification efficiency of the boosted top quark even in a very high pileup condition. Applications to searches for heavy resonances that decay to a final state are also discussed.
