摘要：

We show that rapidity-bin factorial moments contain a large combinatoric contribution from two-particle correlations. In addition, the higher-order correlations are nonnegligible and increase with energy. The analysis is completely general and also applies for the case where the moments scale. We find that the linked-pair approximation (LPA) for higher correlations is valid for UA1 and UA5 data, with coefficients that are approximately independent of energy and somewhat smaller than for the negative binomial distribution.
