Abstract

Starting from a simple empirical parametrization of the scattering amplitude, successfully describing the dip-bump structure of elastic pp scattering in t at fixed values of s, we construct a toy model interpolating between missing energy intervals to extract the Odderon contribution from the difference between p¯p and pp elastic and total cross sections. The model is fitted to data from s=23.5GeV to 7 TeV and used to extract the Odderon and its ratio to the Pomeron. From our fits, a unit intercept Odderon follows, as predicted by J. Bartels, L.N. Lipatov, and G.P. Vacca, on the basis of perturbative quantum chromodynamics.
