Two-particle rapidity correlations between relativistic particles in central collisions of $^{197}$Au nuclei in emulsion at 11.6 A GeV/c

TL;DR

This paper investigates two-particle rapidity correlations in central gold nucleus collisions at high energy, revealing predominantly long-range correlations, and compares experimental data with theoretical models to understand particle production mechanisms.

Contribution

It presents the first detailed analysis of two-particle pseudorapidity correlations in heavy-ion collisions at 11.6 A GeV/c, highlighting the long-range nature of these correlations.

Findings

Long-range pseudorapidity correlations observed in central $^{197}$Au collisions.

Experimental data differ from nucleon-nucleon interaction patterns.

Comparison with models shows partial agreement with FRITIOF-M and independent emission models.

Abstract

It is shown that in central collisions of $^{197}$Au nuclei with heavy emulsion nuclei at 11.6 $A$GeV/c two-particles pseudorapidity correlations for produced particles in terms of correlation functions demonstate predominantly long-range behaviour in contrast to nucleon-nucleon interactions. The experimental data are compared with calculations based on the FRITIOF-M model and the model of independent emission of particles.
