DiJets in Double Pomeron Exchange

CDF Collaboration
Proposed Speaker: Kersten Borras
Abstract
We report the observation of dijet events with a Double Pomeron Exchange topology produced in antiproton-proton collisions at 1800 GeV. The events are characterized by a leading antiproton with a fractional momentum loss Xi in the range 0.035< Xi <0.095 and a four momentum transfer squared |t|<1 GeV2, two jets with transverse energy ET(jet) > 7 GeV in the central pseudorapidity region, and a rapidity gap, defined as a region of pseudorapidity devoid of particles, in the region 2.4< eta <5.9 on the outgoing proton side. Results on jet kinematics, production rates, and comparisons with corresponding results from single diffractive and inclusive dijet production are presented.
