Correlations between azimuthal anisotropy Fourier harmonics in PbPb collisions at root S-NN=2.76 TeV in the HYDJET plus plus model and in the multiphase transport model

Correlations between azimuthal anisotropy Fourier harmonics nu(n) (n = 2, 3, 4) are studied using the events from PbPb collisions at root S-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 nu(n) are measured over a wide centrality range using the two-particle azimuthal correlation method. The slopes of the nu(2)-nu(3) correlation from both models are in a good agreement with the ATLAS data. The HYDJET++ model predicts a stronger slope for the nu(2)-nu(4) and nu(3)-nu(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.
