Dihadron Azimuthal Correlations in 200 GeV Au-Au and 2.76 TeV Pb-Pb Collisions

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