EFFECTS OF SHADOWING IN DOUBLE POMERON EXCHANGE PROCESSES

The effect of shadowing in double Pomeron exchange processes is invest igated within an eikonal approach assuming a Gaussian input. Damping f actors due to screening are calculated for the above process and compa red with results obtained for total, elastic and single diffraction cr oss sections. Our main conclusion is that counting rate calculations, of various double Pomeron exchange processes (without screening correc tions) such as heavy quark and Higgs production are reduced by a facto r of 5 in the LHC energy range, when screening corrections are applied .
