摘要

The anomalous behavior of 2-dimensional scaled factorial moments for charged hadrons in nucleus-nucleus collisions is studied in some detail using both mini-bias and central collision data of 16O- and 197Au-Em interactions from EMU01 experiment. The analysis is carried out in terms of Hurst exponents, suggesting the necessity of different partitions in pseudo-rapidity and azimuthal angle. The results can be interpreted tentatively as due to the superposition effect in nucleus-nucleus collisions.
