Four-lepton resonance at the Large Hadron Collider

Abstract

A spin-1 weakly interacting vector boson, Z ′, is predicted by many new physics theories. Searches at colliders for such a Z ′ resonance typically focus on lepton-antilepton or top-antitop events. Here we present a novel channel with a Z ′ resonance that decays to 4 leptons, but not to 2 leptons, and discuss its possible discovery at the Large Hadron Collider. This baryonic gauge boson is well motivated in a supersymmetry framework. © 2012 American Physical Society.
