We report measurements of the inclusive reaction, pp̄ → pXp̄, in events where either or both the beam-like final-state baryons were detected in Roman-pot spectrometers and the central system was detected in the UA2 calorimeter. A Double-pomeron-Exchange (DPE) analysis of these data and single diffractive data from the same experiment demonstrates that, for central masses of a few GeV, the extracted pomeron-pomeron total cross section, σpptot exhibits an enhancement which exceeds factorization expectations by an order-of-magnitude. This may be a signature for glueball production. The enhancement is shown to be independent of uncertainties connected with possible non universality of the pomeron flux factor. Based on our analysis, we present DPE cross section predictions, for unit (1 mb) pomeron-pomeron total cross section, at the Tevatron, LHC and the 920 GeV fixed-target experiment, HERA-B.
