  A simultaneous description of hadronic yields; pion, kaon, and proton
spectra; elliptic flows; and femtoscopy scales in the hydrokinetic model of A+A
collisions is presented at different centralities for the top BNL Relativistic
Heavy Ion Collider (RHIC) and CERN Large Hadron Collider (LHC) 2.76-TeV
energies. The initial conditions are based on the Glauber Monte-Carlo
simulations. When going from RHIC to LHC energy in the model, the only
parameters changed are the normalization of the initial entropy defined by the
number of all charged particles in most central collisions, contribution to
entropy from binary collisions and baryonic chemical potential. The
hydrokinetic model is used in its hybrid version (hHKM), which provides the
correct match (at the isochronic hypersurface) of the decaying hadron matter
evolution with hadronic ultrarelativistic quantum molecular dynamics cascade.
The results are compared with the standard hybrid models where hydrodynamics
and hadronic cascade are matching just at the non-space-like hypersurface of
chemical freeze-out or on the isochronic hypersurface. The modification of the
particle number ratios at LHC caused, in particular, by the particle
annihilations at the afterburn stage is also analyzed.
