  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.
