摘要：

We report a new measurement of dijet production by color-singlet exchange in p (p) over bar collisions at root s = 1.8 TeV at the Fermilab Tevatron. In a sample of events with two jets of transverse energy E-T(jet) > 20 GeV, pseudorapidity in the range 1.8 < \eta(jet)\ < 3.5, and eta(1) eta(2) < 0, we find that a fraction R = [1.13 +/- 0.12(stat) +/- 0.11(syst)]% has a pseudorapidity gap within \eta\ < 1 between the jets that can be attributed to color-singlet exchnage. The fraction R shows no significant dependence on E-T(jet) or on the pseudorapidity separation between the jets. [S0031-9007(97)05184-3].
