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 <math><msub><mi>v</mi><mn>2</mn></msub></math> and triangular <math><msub><mi>v</mi><mn>3</mn></msub></math> 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 <math><msub><mi>p</mi><mi mathvariant="normal">T</mi></msub></math> and centrality dependencies of quadrangular flow <math><msub><mi>v</mi><mn>4</mn></msub></math> , and also the basic trends for pentagonal <math><msub><mi>v</mi><mn>5</mn></msub></math> and hexagonal <math><msub><mi>v</mi><mn>6</mn></msub></math> flows
