Abstract
After reviewing the evidence for weak simultaneous occurrence of one exclusive and one inclusive pomeron, experiments are described that seek two exclusive pomerons, as well as two exclusive and one inclusive. We discuss the theoretical basis for expecting weak but indefinite pomeron recurrence as the energy increases and outline a systematic rapidly‐converging fireball expansion that brings order to a confusing picture. The widely‐employed two‐component model of particle production corresponds to the two leading terms. An experimentally meaningful concept of “bare” pomeron emerges naturally from the fireball expansion, as does the notion of pomeron renormalization and splitting (the schizophrenic pomeron).
