Blast-wave-Tsallis-power model for $p_{\mathrm{T}}$-spectra and elliptic flow $v_2$ of hadrons in collisions of identical nuclei at energies available at the Large Hadron Collider

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