Fluctuations and correlations in 200A GeV A‐A collisions {au}
Factorial cumulant moments are used to analyze pseudorapidity fluctuations in A‐A interactions. Only the second cumulant moments are significantly non‐zero for central event samples, which implies that the higher order scaled factorial moments for the central data provide little information in addition to that from the second moments. The slopes of the cumulant plots are found to be inversely proportional to η density for a variety of beam/target/energy combinations. We also present results on 2‐D scaled factorial moments and the 2‐particle correlations for central S+Au interactions.
