Rapidity correlations in 800 GeV proton-nucleus interactions

Rapidity correlations in 800 GeV proton interactions with emulsion nuclei a re investigated for different targets and multiplicity regions. To Study th e energy dependence, the results have been compared with proton interaction s at 200 GeV and 400 GeV. A common feature of all the interactions is the e xistence of strong, short-range correlations. However, no dependence of clu ster parameters on primary energy or target mass is found. A marginal incre ase of correlation strength with multiplicity is observed.
