Here, correlations between azimuthal anisotropy Fourier harmonics $$v_n (n$$ = 2 , 3 , 4 ) are studied using the events from PbPb collisions at $$\sqrt{s_\textit{NN}}$$ = 2.76 TeV generated by the HYDJET + + and multiphase transport (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 boomeranglike shape in the structure of the correlations as found in the experimental data.
