Resumo
We construct the Pomeron as an exchange of two nonperturbative gluons, where the nonperturbative gluon propagator is described by an approximate solution of the Schwinger-Dyson equation which contains a dynamically generated gluon mass. We compute the total and elastic differential (dσdt) cross sections for pp scattering, obtaining agreement with the experimental data for a gluon mass m=370 MeV for ΛQCD=300 MeV. In particular, the Pomeron effectively behaves like a photon-exchange diagram with a coupling determined by the gluon mass. © 1993 The American Physical Society.
