Abstract
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.
Highlights
The Large Hadron Collider (LHC) has been probing the physics above the electroweak scale, and the energies of produced massive Standard Model particles such as the weak bosons or top quarks can be much larger than their invariant masses
Within an angle of θ0 ∼ Oð2M=pTÞ along the particle direction where M and pT are the mass and transverse momentum of the particle. These particles can be straightforwardly isolated within a cone of radius Riso ≫ θ0. This forms the basis of the isolation of hadronic τ jets [16,17]1 and extremely boosted weak boson jets at the proposed 100 TeV future circular collider [18,19] where θ0 ∼ 0.02
We show that hadronic jets from decays of even only moderately boosted, color-singlet bosons at the LHC (i.e., θ0 ∼ 0.2–0.4) can be isolated from the rest of the event using telescoping jets and volatility
