- One-particle inclusive distribution in the unitarized pomeron models
Vladyslav Pauk · 2010
High energy inclusive hadron production in the central kinematical region is considered within the models of unitarized pomeron.It is shown that starting from the pomeron contribution with intercept α P (0) > 1 one can obtain in a quasieikonal approach inclusive cross section which is similar to contribution of triple pole (at t = 0) pomeron.Basing on this analogy we then consider general form of tripole and dipole pomeron contribution to inclusive cross section.They lead to a parabolic form of the distribution in rapidity giving ∝ ln 3 s (tripole) or ∝ ln 2 s (dipole).With suggested parametrization of p t dependence of cross sections the considered models well describe the data for charged hadron distributions in pp and pp interactions at energy √ s ≥ 200 GeV.Predictions for LHC energy as well as comparison with a simulation of one particle inclusive production are given.
