Enhancing the heavy Higgs signal with jet-jet profile cuts
Abstract
The jet-jet profile, or detailed manner, in which transverse energy and mass are distributed around the jet-jet system resulting from the hadronic decay of a Z boson in the process Higgs ZZ at a proton-proton collider energy of 40 is carefully examined. Two observables are defined that can be used to help distinguish the +--jet-jet signal from Higgs decay from the ``ordinary'' QCD background arising from the large transverse momentum production of single Z bosons plus the associated jets. By making cuts on these observables, signal to background enhancement factors greater than 100 can be obtained.
