Abstract:

The event-space moments C

_{p,q}

(M) have been calculated using the method of single-event factorial moments. Comparing this with the calculated results for the pure statistical fluctuations Monte-Carlo event sample, the variations of the moments C

_{p,q}

(M) with M are caused dominantly by the statistical fluctuation. The erraticity analysis of the pseudorapidity gaps is performed for the NA27 data. The entropy-like quantities S

_{q}

and Σ

_{q}

are calculated. It is found that S

_{q}

and Σ

_{q}

deviate significantly from 1. S

_{q}

and ∑

_{q}

versus q have exponential behavior. FRITIOF simulation can reproduce the scaling behavior, but the deviations of the values from the experimental data are rather large.
