PHOTON – POMERON COUPLING IN HADRONIC INTERACTIONS

Pomeron coupling to photons has been analyzed. as the pomeron assumed to couple to hadrons through their constituent quarks and since the photon has no constituent quarks it's coupling to the pomeron is not well known. we proposed that the pomeron may couple to two photons in away similar to that of pseudo scalar particles (π0, η, ή ). to justify our model we have calculated the photon-proton total cross section in the region where a single pomeron is dominated. for completeness the contribution from reggeons exchange at low energies has been included. a comparison with the data shows a good agreement
