Abstract

We present the results of an analysis of two charged particle and transverse energy correlations in Si+Pb collisions at BNL AGS at 14.6 GeV/c per nucleon. The measured semi-inclusive normalized two-particle pseudorapidity correlation function exhibits short-range correlations similar to the correlations observed in hadron-hadron and hadron-nucleuscollisions at higher energies, although the observed correlations aresmaller than the values scaled from hp and hA data. Estimates, provided by the observed correlations, of the intermittency indices as well as of the parameters of the cluster model are presented. Predictions using the FRITIOF event generator, which at this level of statistical accuracy show no pseudorapidity correlations, are not in agreement withour data. Azimuthal angle two-particle correlations show nonzero back-to-back correlations in the central region (consistent with FRITIOF predictions) and are almost flat in the projectile fragmentation region. We also present results on the transverse energy azimuthal correlation function, which are similar to those from the two-particle correlation function.
