PHENOMENOLOGICAL IMPLICATIONS OF A PERTURBATIVE POMERON BEYOND THE DIPOLE APPROXIMATION

Assuming that the bare Pomeron is a ''perturbative'' series of Regge m ultipoles, we investigate phenomenological consequences of an extensio n of the dipole Pomeron model by including corrections from a tripole. Reasonable fits to the pp and ppBAR scattering data are obtained. The improvement over similar fits based on a dipole model are visible in the dip region and at large Absolute value of t. The knowledge of the fitted parameters is important for the reconstruction of the assumed p erturbative series of multipole Pomerons.
