One- and two-particle inclusive distributions in pion- and proton-nucleus interactions at 300 GeV

We report the data on 300 GeV pion-emulsion-nucleus reactions and compare the results to proton-emulsion-nucleus reactions at the same energy. In particular we present results on the one- and two-particle inclusive pseudorapidity distributions. Two-particle distributions are investigated by using the correlation function formalism. The dependence of one-particle inclusive spectra on the projectile and nuclear excitation obeys scaling. Short-range correlations are observed for pairs of charged particles. No differences are observed between the analogous correlations in pion- and proton-nucleus interactions.
