Abstract:
The self-affine analysis and erraticity analysis of pseudorapidity gaps are performed for the data of 400GeV/ pp collisions. The self-affine analysis has been shown to exhibit a better scaling behavior. The self-affine multifractal dimensions and multifractal spectrum have been obtained. The simulated results using FRITIOF program can not reproduce the scaling behavior. The analysis of event-to-event fluctuations has been performed. The increase of event-space moments with decreasing phase-space scale is dominated by the statistical fluctuations. The erraticity analysis based on measuring the pseudorapidity gaps is also performed. The entropy-like quantities and deviate from 1 significantly, implying that both of them are useful to serve as effective measures of erraticity in multiparticle production. The ln versus has a quite linear behavior, but the ln versus has only an approximate linear behavior. The FRITIOF simulated results follow the same scaling behavior, but the deviations from the experimental data are rather large.- talk: Datong 2001/09/01
