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

الملخص EN

In a multisource thermal model, we detailedly show dihadron azimuthal correlations for 20–40% and 50–80% in Au-Au collisions at sNN=200 GeV and over a centrality range from 10–15% to 70–80% in Pb-Pb collisions at sNN=2.76 TeV.

The model can approximately describe the azimuthal correlations of particles produced in the collisions.

The px amplitude of the corresponding source is magnified, and the source translates along the direction.

The factor αx, in most cases, increases with the increase of the centrality in Pb-Pb collisions at sNN=2.76 TeV.
