Descripción
The hydrodynamic extension of the two component model for hadroproduction using recent theoretical calculations is suggested to describe the spectra of charged particles produced in heavy-ion collisions in the full range of transverse momenta, $p_T$. Data from heavy-ion collisions measured at RHIC and LHC are analyzed using the introduced approach and are combined in terms of energy density. The Boltzmann-like statistical distribution taking into account the 'collective flow' effects stands for the radiation of the thermalized particles, while the power-like term describes charged hadron production in pQCD. The observed regularities give understanding of the peculiar shape of the nuclear modification factor, $R_{AA}$, as function of transverse momentum, $p_T$, and may be explained by the formation of QGP during the collision. Finally, the extracted dependences are used to make predictions for further LHC measurements at $\sqrt{s} = 5.5$ Tev/N.
