We report a measurement of the fraction of dijet events with a rapidity gap between jets produced by color-singlet exchange in (p) over bar p collisions at root s = 630 GeV at the Fermilab Tevatron. In events with two jets of transverse energy E-T(jet) > 8 GeV, pseudorapidity in the range 1.8 < \n(jet)\ < 3.5 and eta(1)eta(2) < 0, the color-singlet exchange fraction is found to be R = [2.7 +/- 0.7(stat) +/- 0.6(syst)]%. Comparisons are made with results obtained at root s = 1800 GeV and with theoretical expectations.

Abstract

We report a measurement of the fraction of dijet events with a rapidity gap between jets produced by color-singlet exchange in (p) over bar p collisions at root s = 630 GeV at the Fermilab Tevatron. In events with two jets of transverse energy E-T(jet) > 8 GeV, pseudorapidity in the range 1.8 < \n(jet)\ < 3.5 and eta(1)eta(2) < 0, the color-singlet exchange fraction is found to be R = [2.7 +/- 0.7(stat) +/- 0.6(syst)]%. Comparisons are made with results obtained at root s = 1800 GeV and with theoretical expectations.
