$J_{E_T}^{\rm II}$: A Two-prong Jet Finding Algorithm

We propose a new global jet-finding algorithm for reconstructing two-prong objects like hadronic weak gauge bosons at a hadron collider. The selection of particles in a two-prong jet is required to maximize a $J_{E_T}^{\rm II}$ function, which contains a modified second Fox-Wolfram moment and prefers a two-prong structure for a fixed jet mass. Compared to the traditional jet-substructure method, our algorithm can provide a similar or better performance for identifying boosted weak gauge bosons that are produced from either Standard Model processes or heavy di-boson resonance decays.
