[en] Hadron production in diffraction dissociation is studied in a model which includes hard diffraction and soft hadron interaction as controlled by a supercritical pomeron. Rapidity gaps between jets are obtained by soft color recombination (SCR). It was previously shown that this model is able to describe data on diffractive hadron production from the CERN-SPS collider and from the HERA lepton-proton collider. Here we present model predictions for rapidity gap events in p-p collisions at √s = 1800 GeV and compare to TEVATRON data
