Inclusive distributions in the unitarized pomeron models

Abstract

High energy inclusive hadron production in the central kinematical region is analyzed within the models of unitarized pomeron. It is shown that the sum of multipomeron exchanges with intercept αP(0)>1\alpha_P(0)>1 reproduce qualitatively contribution of the triple pole (at t=0t=0) pomeron to inclusive cross section. Basing on this analogy we then suggest a general form of unitarized pomeron contributions (in particular the dipole or tripole pomeron) to inclusive cross section. They lead to a parabolic form of the rapidity distribution giving <n>ln3s<n>\propto \ln^3s (tripole) or <n>ln2s<n>\propto \ln^2s (dipole). The models considered with suggested parametrization of ptp_t-dependence for cross sections well describe the rapidity distributions data in pppp and pˉp\bar pp interactions at energy s200\sqrt{s}\geq 200 GeV. The predictions for one particle inclusive production at LHC energies are given.
