Abstract：
The dynamical fluctuations in 3 different samples of 630 GeV/c proton-antiproton collisions are studied using Monte Carlo method. These are the mini-bias event sample, the jetty event sample and the sample consisting of the hadrons inside jets. The jets are identified using cone-algorithm. The results show that the jetty event sample mimic the whole event sample in high energy e⁺e^－ collisions has isotropic dynamical fluctuations, while the dynamical fluctuations inside jets are similar to those of the soft hadronic collisions, being isotropic in the transverse plane but anisotropic in the longitudinal-transverse planes. This shows that the production and evolusion of jets (minijets) have similar dynamical fluctuation property as the production and evolusion of jets in e⁺e^－ collisions, respectively.
The mini-bias event sample is a mixture of the jet-production processes of hard (semi hard) parton collisions and the soft hadron hadron collision processes. Therfore, it does not have simple dynamical fluctuation property.
