Description

We calculate the mass distribution (dσ/dMX) as observed by the UA8 Collaboration in the inclusive reaction pp-bar→pXp-bar at √(s)=630 GeV, using the interacting gluon model (IGM) with double Pomeron exchange (DPE) included. The only new parameter is the P-P cross section, which we can extract from fitting experimental data. We compare our results with the values obtained in the UA8 study. Assuming a constant Pomeron-Pomeron total cross section (σPP=1 mb), we make predictions for dσ/dMX at Fermilab Tevatron and CERN LHC energies
