On a Qualitative Difference between the Dynamics of Particle Production in Soft and Hard Processes of High Energy Collisions
Liu Feng, Liu Fuming, Liu Lianshou
Abstract
The qualitative difference between the anomalous scaling properties of hadronic final states in soft and hard processes of high energy collisions is studied in some detail. It is pointed out that the experimental data of e+e- collisions at Ecm=91.2 GeV from DELPHI indicate that the dynamical fluctuations in e+e- collisions are isotropical, in contrast to the anisotropical fluctuations oberserved in hadron-hadron collision experiments. This assertion is confirmed by the Monte Carlo simulation using the Jetset7.4 event generator.
