Dihadron Azimuthal Correlations inp-pCollisions atsNN=7 TeV andp-Pb Collisions atsN

Abstract

The dihadron azimuthal correlations inp-pcollisions atsNN=7 TeV andp-Pb collisions atsNN=5.02 TeV are investigated in the framework of a multisource thermal model. The model can approximately describe the experimental results measured in the Large Hadron Collider. We find thepxamplitude of the source is magnified and the source translates along the direction.

Azimuthal correlations of particles in a non-central rapidity region in high energy heavy ion collisions

“…The understanding of those processes and interactions is quite limited theoretically in soft non-pertubative regime due to the lack of knowledge based on first principles, and thus mainly rely on some models, e.g. the string percolation model [13], multisource thermal model [14], the two-source 'jet/flow' model [15] and the correlated emission model [16], etc. Based on some models, the azimuthal correlations can be used to extract information of multi-parton dynamics in the non-pertubative regime.…”
