Title: Diffractive Dijets with a Leading Antiproton in p(bar sign) p Collisions at {radical}(s) =1800 GeV

Abstract

We report results from a study of events with a leading antiproton of beam momentum fraction 0.905<x{sub F}<0.965 and 4-momentum transfer squared |t|<3 GeV{sup 2} produced in p(bar sign) p collisions at {radical}(s)=1800 GeV at the Fermilab Tevatron collider. Approximately 2% of the events contain two jets of transverse energy E{sup jet}{sub T}>7 GeV . Using the dijet events, we evaluate the diffractive structure function of the antiproton and compare it with expectations based on results obtained in diffractive deep inelastic scattering experiments at the DESY ep collider HERA.
