Correlations between azimuthal anisotropy Fourier harmonics in PbPb collisions at $\sqrt{s_{{}_{\mathrm{NN}}}}=2.76$ TeV in the HYDJET++ and AMPT models

Abstract

Correlations between azimuthal anisotropy Fourier harmonics $v_n$ ($n=2,3,4$) are studied using the events from PbPb collisions at $\sqrt{s_{{}_{\mathrm{NN}}}}=2.76$ TeV generated by the HYDJET++ and AMPT models, and compared to the corresponding experimental results obtained by the ATLAS Collaboration. The Fourier harmonics $v_n$ are measured over a wide centrality range using the two-particle azimuthal correlation method. The slopes of the $v_2$--$v_3$ correlation from both models are in a good agreement with the ATLAS data. The HYDJET++ model predicts a stronger slope for the $v_2$--$v_4$ and $v_3$--$v_4$ correlations than the ones experimentally measured, while the results from the AMPT model are in a rather good agreement with the experimental results. In contrast to the HYDJET++ predictions, the AMPT model predicts a boomerang-like shape in the structure of the correlations as found in the experimental data.
