Detection of phase transition signal ''hadrons-???'' in inelastic p bar p-collisions in track UA5 and CDF experiments

Description

Based on Saleh-Teich cascade-stochastic formalism the naieve cascade model of multiple charged particles production in inelastic hadron-hadron collisions at high energies is offered. It is shown that the multiplicity charged particles distributions in inelastic p bar p- and pp-collisions in all the range of ISR- and Sp bar pS energies up to the energy of Fermilab Tevatron Collider √s=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 behavior of multiplicity KNO-distributions of charged particles produced in hadron collisions, namely KNO-scaling is well satisfied in the energy range √s=21.7-62.2 GeV and at ultrahigh energies starting from energy of Tevatron Collider √s=1800 GeV, but it is completely violated in the energy range √s=200-900 GeV. The analysis of the distribution function of intervals between two series of finite events made it possible to reveal a super Poisson nature of degree of hadron events grouping at √s=540 GeV. Research 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 bar interactions at Sp bar pS-collider energies over 540 GeV√ s ∼770 GeV)
