Abstract
Based on Saleh-Teich cascade-stochastic formalism the naive cascade model o f multiple charged particles production in inelastic hadron-hadron collisio ns at high energies is offered. It is shown that the multiplicity charged p articles distributions in inelastic (p) over barp- and p p-collisions in al l the range of ISR- and S (p) over bar -pS energies up to the energy of Fer milab Tevatron Collider roots = 1800 GeV are well described by Salech-Teich 's three-parametrical distribution belonging to a special class of Markov's (generally inhomogeneous) branching Neyman-Scott processes. The properties of ST-distribution made it possible to detect anomalous beha vior of multiplicity KNO-distributions of charged particles produced in had ron collisions, namely KNO-scaling is well satisfied in the energy range ro ots = 21.7-62.2 GeV and at ultrahigh energies starting from energy of Tevat ron Collider roots = 1800 GeV, but it is completely violated in the energy range roots = 200-900 GeV. The analysis of the distribution function of intervals between two series o f finite events made it possible to reveal a super Poisson nature of degree of hadron events grouping at roots greater than or equal to 540 GeV. Resea rch of KNO-scaling anomalous behavior and degree of finite hadrons grouping (made within the framework of known UA5- and CDF-experimental multiplicity distributions) is indicated as emerging from a signal of phase transition "hadron matter-???" in inelastic (p) over barp-interactions at S (p) over b ar -pS-collider energies over 540 GeV(roots approximate to 770 GeV).
