Baryon Transport in Dual Models and the Possibility of a Backward Peak in Diffraction

Abstract

Dual string models contain significant baryon transfers and seem essentially consistent with the available data. We here turn to a careful consideration of the relevant topological structures. The baryon transfer is associated with one of two possible types of cuts in various baryonium exchanges. As the baryonium with the highest intercept easily couples to two Pomerons such transfers should occur abundantly in percolating dense Pomerons systems. From the color structure this quark-less baryonium can be identified with an Odderon exchange. As the Odderon is predicted to have an almost Pomeron -like trajectory it has to involve small coupling constants so that steeper trajectories can initially determine the data. As this suppression is not anticipated for diffractive processes a tiny observable backward peak should occur in the initial baryon distribution for massive diffractive systems.
