Events with a Rapidity Gap between Jets in p¯p Collisions at √s=630 GeV Academic Article uri icon


  • We report a measurement of the fraction of dijet events with a rapidity gap between jets produced by color-singlet exchange in pp collisions at √s=630GeV at the Fermilab Tevatron. In events with two jets of transverse energy EjetT > 8GeV, pseudorapidity in the range 1.8 <|ηjet|< 3.5 and η1η2<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 √s=1800GeV and with theoretical expectations. © 1998 The American Physical Society.
