摘要：

It is shown for a simple model ("α-model") realizing a self-similar random cascade process in d=2 (or d=3) dimensions of momentum space that intermittency of the multiplicity distribution occurs in the d-dimensional analysis but disappears in the one-dimensional projection. This demonstrates the importance of multidimensional analysis for the interpretation of data in terms of intermittency. However, in a variety of two- and three-dimensional cascade models a power-type relation between moments remains for the one dimensional projection into rapidity space and these relations are supported by data from all collision processes in the full rapidity range. The difference to the negative binomial description is pointed out. © 1990.
