Abstract

Two distinct interactions of Pomerons should occur in dense multi-string events. Besides the usual triple Pomeron processes transitions to membraned cylinders can be expected to contribute in a significant way. They offer an efficient mechanism for central baryon production and for the long range transport of initial baryons. The slope of such an exchange should be quite low as it is related to the Odderon known from the leading logarithmic approximation. Such a flat trajectory has to be suppressed by small coupling constants. It is argued that this strong suppression does not appear in diffractive events. In consequence there should be a tiny observable backward peak in the initial baryon distribution even in quite massive diffractive systems.
