Abstract

In a multisource thermal model, we detailedly show dihadron azimuthal correlations for 20–40% and 50–80% in Au-Au collisions atsNN=200 GeV and over a centrality range from 10–15% to 70–80% in Pb-Pb collisions atsNN=2.76 TeV. The model can approximately describe the azimuthal correlations of particles produced in the collisions. Thepxamplitude of the corresponding source is magnified, and the source translates along the direction. The factorαx, in most cases, increases with the increase of the centrality in Pb-Pb collisions atsNN=2.76 TeV.

Summary

Introduction

An important subject of high energy physics is to discuss the strongly interacting matter and nuclear matter at high temperature and high density by heavy-ion collisions at ultrarelativistic energies [1, 2]. In the initial stage of the collision, tremendous amounts of energy are accumulated at a finite zone in a short time They result in the creation of a nearly perfect quark-gluon plasma (QGP), which will undergo the hadronization and freeze-out and will produce lots of observed particles [3]. Some theoretical investigations [5,6,7,8,9,10] give many valuable and interesting results to explain the ridge phenomena, which were regarded as a contribution from jet-medium interactions. In these works, various models have been proposed.
