| contents | A generalization of the phenomenological blast-wave-Tsallis-power model, recently proposed by the author for the hadrons transverse momentum ($p_\textrm{T}$) spectra measured at the LHC, is developed to also describe the hadrons $p_\textrm{T}$-differential elliptic flow coefficients $v_2$ in identical nuclei collisions of different centralities. The model describes well the available data on $p_\textrm{T}$-spectra and $v_2$ for any $p_\textrm{T}$ of various particles, from pions to charmonia, in Pb--Pb at $\sqrt{s_\mathrm{NN}}=$ 2.76 and 5.02~TeV, and in Xe--Xe at $\sqrt{s_\mathrm{NN}}=$ 5.44~TeV. Also, predictions for OO collisions at $\sqrt{s_\mathrm{NN}}=$ 5.36~TeV are given. While the model is mainly targeting the LHC energies, it also works at much lower RHIC energies. |
