Abstract

Using the HYDJET++ model, we measure the higher-order flow harmonics v_n(n=2,3,4) of (multi-) strange hadrons in Au+Au collisions at √s_NN = 200 GeV and Pb+Pb collisions at √s_NN = 2.76 TeV. We have compared our model results and experimental data at RHIC and LHC energies. The model reproduces the higher flow harmonics of (multi-) strange hadrons as a function of p_T, centrality, and quark content. We have studied and discussed mass ordering of flows v_n(n=2,3,4) among π⁺+π^-, K^-+K⁺, K_s⁰, p+p, Λ+Λ, Ξ^-+Ξ⁺, Ω^-+Ω⁺ at low p_T and the baryon-meson grouping at intermediate p_T. NCQ scaling using the HYDJET++ model and its comparison with experimental results at RHIC and LHC energies have also been discussed. Study of flow harmonics behaviour in RHIC and LHC energy regimes will provide an additional insight into the dynamics of anisotropic flow and the effect of radial flow expansion in the system.
