Abstract

The LHC data on azimuthal anisotropy harmonics from PbPb collisions at center-of-mass energy 2.76 TeV per nucleon pair are analyzed and interpreted in the framework of the HYDJET++ model. The cross-talk of elliptic v₂ and triangular v₃ flow in the model generates both even and odd harmonics of higher order. Comparison with the experimental data shows that this mechanism is able to reproduce the p_{\rm T} and centrality dependencies of quadrangular flow v₄, and also the basic trends for pentagonal v₅ and hexagonal v₆ flows.
