Abstract
A fit for photon-proton total cross section ( ) data in terms of Regge model has been obtained. As usual the fit can be obtained by calculating the coupling constants of the exchanged Reggeons and pomerons in the process. The model has three Regge components, the low energy region is dominated by meson and the high energy region is dominated by the soft and hard pomerons. As Regge pole factorizes the hadronic total cross sections are related by factorization. A fit for the photon -photon total cross section ( ) can also be obtained by the factorization.
