We determine the 4-jet contribution in e-e+ collisions of heavy scalar diquarks from E6 compactification in superstring theories. For CM energy √s>150 GeV the signal exceeds the QCD background (for √s>200 GeV by an order of magnitude or more). At the Z0 peak the background somewhat exceeds the signal, but we show that measured cross sections are sensitive to this contribution for diquark masses up to ∼45 GeV.
