In two-particle angular correlation measurements, the distribution of charged hadron pairs are evaluated as a function of pseudorapidity (
) and azimuthal (
) differences. In these correlations, jets manifest themselves as a near-side peak around
. These correlations can be used to extract transverse momentum (
) and centrality dependence of the shape of the near-side peak in Pb-Pb collision. The shape of the near-side peak is quantified by the variances of the distribution. The variances are evaluated from a fit combining the peak and the background. In this contribution, identified and unidentified angular correlations are shown from Pb-Pb collisions at
TeV from Monte Carlo simulations (AMPT, PYTHIA 8.235/Angantyr). Results show that transport models in AMPT give better results than PYTHIA 8.235/Angantyr when comparing to the experimental results of the ALICE collaboration.
