EFFECTS OF SHADOWING IN DOUBLE POMERON EXCHANGE PROCESSES

The effect of shadowing in double Pomeron exchange processes is investigated within an eikonal approach assuming a Gaussian input. Damping factors due to screening are calculated for the above process and compared with results obtained for total, elastic and single diffraction cross sections. Our main conclusion is that counting rate calculations, of various double Pomeron exchange processes (without screening corrections) such as heavy quark and Higgs production are reduced by a factor of 5 in the LHC energy range, when screening corrections are applied.
