Abstract

Analysis of correlation of multiplicities between various rapidity bins is carried out in the framework of a superposition approach consisting of three phases of the ultrarelativistic nuclear collision: early partonic phase, intermediate collective evolution, and statistical hadronization. Simple relations between the moments of produced hadrons and the moments of the sources produced in the initial partonic phase are presented. They involve only a few effective parameters describing the microscopic dynamics of the system. We illustrate the practicality of the approach with the Glauber model simulations. Our study bears direct relevance to the interpretation of the upcoming results for the multibin multiplicity correlations from the CERN Large Hadron Collider, which will help in an assessment of the correlation features of the state formed in the earliest stage of the reaction.
