Φ-measure in high energy heavy-ion collisions

Event-by-event fluctuations for high energy heavy-ion collisions are investigated. The normally used Φ-measure are calculated for pions. It was shown that multiparticle symmetrization (antisymmetrization) correlation has great influence on the value of Φ if the phase space density is high. Previous derivation of Φ actually neglected the multiparticle quantum correlation. So the explanation of Φ...

Event – by – event fluctuations in heavy – ion collisions and the quark – gluon string model

We apply dynamical string models of heavy–ions collisions at high energies to the analysis of event–by–event fluctuations. Main attention is devoted to a new variable proposed to study ”equilibration” in heavy–ions collisions. Recent results of the NA49 collaboration at CERN SPS are compared with predictions of the Quark–Gluon String Model (QGSM), which gives a good description of different asp...

Moments of event observable distribution in high energy heavy-ion collisions

Event-by-event fluctuations for high energy heavy-ion collisions are investigated. The normally used Φ-variables are calculated for pions. It was shown that multiparticle symmetrization (antisymmetrization) correlation has great influence on the value of Φ. Previous derivation of Φ actually neglected the multiparticle quantum correlation. So the explanation of Φ as a measure of the degree of eq...
