Description
Hydro-kinetic approach for the dynamics A+A collision describes gradual destruction of local equilibrium in hydrodynamically expanding medium due to particle liberation in a way consistent with Boltzmann equation and conservation laws. Such an approach can be used also as non-equilibrated input for subsequent  hadronic cascade stage. In this talk we present the recent results of calculations in hybrid hydro-kinetic model, where particle interactions at the latest stage of collision are treated with transport code (UrQMD).  We present the results on transverse spectrum, elliptic flow and interferometry radii for Au+Au collisions at top RHIC energy and Pb+Pb collisions at 2.76 A GeV LHC energy. We show the influence of a switching procedure from hydro to kinetic models (HKM procedure versus standard one, based on Cooper-Frye prescription) on the results.  The peculiarities of the initial stage, allowing one to reach simultanious description  of the pion, kaon and proton spectra, their anisotropy and pion femtoscopy scales in central and non-central collisions, are discussed.
