Book Description
We present new evidence for events with a rapidity gap between jets in {bar p}-p collisions at (square root)s = 1.8 TeV based on data collected by triggering the Collider Detector at Fermilab on two high transverse momentum forward jets and results of a search for diffractive W" and dijet production where diffraction is tagged by the rapidity gap technique. We also present the results of a search for diffractive dijets using data collected by triggering on a very forward particle in the recently installed roman-pot detectors. The dijet events exhibit additional diffractive characteristics such as rapidity gaps and boosted center of mass system, however the recoil antiproton measured in the roman-pots is in a regime in which the non- pomeron contribution is significant.

We present final results by the CDF II collaboration on diffractive W and Z production, report on the status of ongoing analyses on diffractive dijet production and on rapidity gaps between jets, and briefly summarize results obtained on exclusive production pointing to their relevance to calibrating theoretical models used to predict exclusive Higgs-boson production at the LHC.

Book Description
We present the[eta] and E[sub T] dependence of dijet events produced by color-singlet exchange in[anti p]p collisions at[radical]s= 1.8 TeV using data collected by the CDF collaboration at the Fermilab Tevatron. In a sample of events with two forward jets, where the jets are on opposite sides in rapidity with[vert-bar][eta][vert-bar]> 1. 8 and E[sub T]> 20 GeV, we find 1.13[+-] 0.12(stat)[+-] 0. 11(syst)% have a rapidity gap between the jets consistent with color- singlet exchange. This signal has no significant dependence on the jet E[sub T] or the rapidity interval between the jets.

Book Description
We have studied events with a high-x{sub F} antiproton and two central jets in CDF, with p{anti p} collisions at √s = 630 and 1800 GeV. These events are expected to be dominated by diffraction (pomeron exchange). The jet E{sub T} spectra are very similar to those of non-diffractively produced jets but slightly steeper; their azimuthal difference [Delta][phi] is more peaked at 180°.

Rapidity Gaps in Jet Events at D{O}

Book Description
Preliminary results from the D0 experiment on jet production with rapidity gaps in p{bar p} collisions are presented. A class of dijet events with a forward rapidity gap is observed at center-of-mass energies (square root)s = 1800 GeV and 630 GeV. The number of events with rapidity gaps at both center-of-mass energies is significantly greater than the expectation from multiplicity fluctuations and is consistent with a hard single diffractive process. A class of events with two forward gaps and central dijets is also observed at 1800 GeV. This topology is consistent with hard double pomeron exchange. We also present results on the observation of a class of events with low particle multiplicity between jets, attributable to the exchange of a strongly-interacting color-singlet.
