Abstract

A comprehensive study of forward elastic proton-proton scattering over a wide energy range 10 ≤ s ≤ 3000 GeV2, is carried out in terms of s-channel helicity amplitudes. A hybrid model is constructed in which the pomeron exchange is represented by the sum of Bessel functions parameterizing the proton core and periphery; this is augmented by the exchange of Regge trajectories which contribute to the helicity single and double flip amplitudes, and have a dynamical dependence determined by a cylindrical Bessel function of order one. Our model yields a reasonable fit simultaneously to the measured total and differential cross sections, the ratio of Re ø1(s, 0)/Im ø1(s, 0), the polarization and correlation tensor in the energy range mentioned above, and for momentum trasfer squared values, -t < 3 GeV2.
