Geometrical scaling, quarks and the Pomeron

From quark model additivity applied in the impact parameter plane to the inelastic overlap function we obtain a kind of scale invariant factorizable Pomeron. Quarks themselves are seen as behaving asymptotically like extended objects (quark pancakes), cross-sections and multiplicities being related to their overlap in a high energy collision. Predictions, which can be tested soon at NAL, are given for overlap functions, cross-sections, the ratio σsup(el)/σsup(tot) in the case of various reactions. Universality features of multiplicity distributions are explained in a natural way and an attempt is made to compute the modifications coming from the leading particle effect. (author)
