The Influence of Statistical Fluctuations on Erraticity Behavior of Multiparticle System
Fu Jinghua, Wu Yuanfang, Liu Lianshou
Abstract
It is demonstrated that in low multiplicity sample, the increase of the fluctuation of event-factorial-moments with the diminishing of phase space scale, called ``erraticity'', are dominated by the statistical fluctuations. The erraticity behavior observed at NA27 experiment can be readily reproduced by pure statistical fluctuations. Applying erraticity analysis to a high multiplicity sample is recommended and the method is improved at very high multiplicity case as well.
