Isolating color-singlet boson jets at the LHC using telescoping jet substructure

摘要

We demonstrate that jets from hadronic decays of moderately boosted color-singlet bosons at the LHC can be isolated. The telescoping jet substructure method is used to carve out dominant energy flows along subjets and identify the radiation surrounding the dipole, and it achieves excellent performance in identifying boosted W boson and top quark jets at the LHC energy. We show that telescoping jet variables efficiently isolate subjets, and we compare with standard N-prong taggers and isolation cone methods.
