Abstract
The jet-jet profile, or detailed manner, in which transverse energy an d mass are distributed around the jet-jet system resulting from the ha dronic decay of a Z boson in the process Higgs boson-->ZZ at a proton- proton collider energy of 40 TeV is carefully examined. Two observable s are defined that can be used to help distinguish the l+l--jet-jet si gnal from Higgs boson decay from the ''ordinary'' QCD background arisi ng from the large transverse momentum production of single Z bosons pl us the associated jets. By making cuts on these observables, signal to background enhancement factors greater than 100 can be obtained.
