Abstract
We reanalyse and high energy data of the elastic scattering above GeV on the total cross-section and on the forward -ratio for various models of Pomeron, utilizing two methods. The first one is based on analytic amplitudes, the other one relies on assumptions for and on dispersion relation for . We argue that it is not possible, from fitting only existing data for forward scattering, to select a definite asymptotic growth with the energy of . We find equivalent fits to the data together with a logarithmic Pomeron giving a behavior , and with a supercritical Pomeron giving a behavior , .
