Comparison shows agreement/discrepancies with Pythia and Phojet simulations.

Insights into particle production mechanisms in high-energy collisions.

Abstract

We present results from the measurements of azimuthal correlations of charged particles in $\sqrt{s_{_{NN}}}$ = 2.76 TeV Pb--Pb collisions and $\sqrt{s_{_{NN}}}$ = 7 TeV pp collisions. In addition, the comparison of the experimental measurements in pp collisions with those from Pythia and Phojet simulations are presented.
