Book excerpt: Fluctuations in pseudorapidity of charged particle multiplicity from central (ZCAL) collisions of [sup 16]O+Cu at 14.6 A[center-dot]GeV/c have been analyzed by the E802 Collaboration using the method of normalized factorial moments as a function of the interval [delta][eta]. In agreement with previous measurements, an apparent power-law growth of moments with decreasing interval is observed down to [delta][eta] [approximately] 0.1. Experience with E[sub T] distributions suggests that fluctuations of multiplicity and transverse energy can be well described by Gamma or Negative Binomial Distributions (NBD) and excellent fits to NBD were obtained in all [delta][eta] bins. The [kappa] parameter of the NBD fit was found to increase linearly with the [delta][eta] interval, which due to the well known property of the NBD under convolution, indicates that the multiplicity distributions in adjacent bins of pseudorapidity [delta][eta] [approximately] 0.1 are largely statistically independent.
