Title: A model for the differactive background of ππ scattering
Abstract: A model for the diffractive background of ππ scattering is constructed, satisfying analyticity and crossing symmetry. The corresponding amplitude, which represents the exchange of a non-flat Pomeron, gives appreciable contributions to the small s, t and u-region. But it is still possible to fulfil Adler's condition, to obtain the scattering lengths predicted by current algebra, and to saturate the Adler-Weisberger sum rule, when such a term is added to the Veneziano amplitude with the “experimental” ϱ-trajectory (αϱ(0) = 0.56).
