Abstract
We present results on dijet production via hard color-singlet exchange in proton-antiproton collisions at root s = 630 GeV and 1800 GeV usin g the D empty set detector. The fraction of dijet events produced via color-singlet exchange is measured as a function of jet transverse ene rgy, separation in pseudorapidity between the two highest transverse e nergy jets, and proton-antiproton center-of-mass energy. The results a re consistent with a color-singlet fraction that increases with an inc reasing fraction of quark-initiated processes and inconsistent with tw o-gluon models for the hard color-singlet.
