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

The data on 300 GeV pion-emulsion-nucleus reactions are reported and the results to proton-emulsion-nucleus reactions at the same energy are compared. In particular results on the one- and two-particle inclusive pseudorapidity distributions are presented. 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 (ν) 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
