Simulation of the multi particle production with statistical model

Among the multiple production phenomena of high energy hadrons from e+e- annihilation to nucleus-nucleus collision, particularly the construction of the model that can describe the physical quantities related to fluctuation and multi-particle correlation was aimed at. There is the possibility that the actually observed distribution of hadrons does not depend on dynamic details. Therefore, the extended statistical model based on entropy-maximizing method, in which free parameter is one, was used. In the analysis of this time, the reaction was limited to e+e- annihilation, and this model was compared with the experiment for different energy values. The outline of this model, the method of simulation and the results of comparison are reported, and the problems and the subjects for hereafter are discussed. The statistical model based on entropy-maximizing method is explained. The results of calculation are shown, which agreed well with the experiment. Also the distributions of the degree of multiplicity and rapidity, factorial moment, Bose-Einstein correlation and the energy dependence of dispersion are shown. (K.I.)
