Higher harmonics of azimuthal anisotropy in relativistic heavy ion collisions in HYDJET++ model
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 T and centrality dependencies of quadrangular flow v4, and also the basic trends for pentagonal v5 and hexagonal v6 flows.
