Higher harmonics of azimuthal anisotropy in relativistic heavy-ion collisions in HYDJET++ model

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 $$v_2$$v2 and triangular $$v_3$$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 $$p_\mathrm{T}$$pT and centrality dependencies of quadrangular flow $$v_4$$v4, and also the basic trends for pentagonal $$v_5$$v5 and hexagonal $$v_6$$v6 flows.
