Sažetak

Some results of the investigation of processes of multiple production in the framework of field-theory models, using the Feynman-Bogoljubov functional integral method, are given. By the use of the straight-line path approximation it is shown that the N meson production amplitude is factorized and a multiplicity distribution of the Poisson type is obtained. An interesting relation between the multiplicity of secondary particles, the slope of the diffractional peak, and the total cross section is obtained. By a simple assumption about the isospin structure the model is used to fit the charged particle multiplicity distribution for both , π^-p and , π^-n scattering at 40 GeV.
