Abstract
The qualitative difference between the anomalous scaling properties of hadr onic final states in soft and hard processes of high-energy collisions is s tudied in some detail. It is pointed out that the experimental data of e(+) e(-) collisions at E-c.m.=91.2 GeV from DELPHI indicatethat the dynamical f luctuations in e(+)e(-) collisions are isotropical, in contrast with the an isotropical fluctuations oberserved in hadron-hadron collision experiments. This assertion is confirmed by the Monte Carlo simulation using the JETSET 7.4 event generator. [S0556-2821(99)00911-X].
