Diffraction Production of Bosons

A simple qualitative model for hadronic two-body amplitudes is discussed.The model combines the two-component theory of duality with the main idea:+of the absorption model. The imaginary parts of all two-body hadronic ampli-tudes are described as a sum of two componenfs a Pomeron term dual tothe s-channel background, and an ordinary exchange term dual to the s-channelresonances. The latter term is assumed to be dominated by the most periph-eral partial waves within the range of interaction (Q qr, where q is the c. m.momentum ; r 1 fermi) . The model reproduces correctly the qualitativefeatures of the elastic differential cross sections and polarizations as well asthe dip systematics of inelastic two-body reactions.ReferencesH.
