Transverse Spectra of Hadrons in Central $AA$ Collisions at RHIC and LHC   from pQCD+Saturation+Hydrodynamics and from pQCD+Energy Losses
  We study the transverse spectra of hadrons in nearly central $AA$ collisions at RHIC and LHC in a broad transverse momentum range Low-$p_T$ spectra are calculated by using boost-invariant hydrodynamics with initial energy and net-baryon densities from the EKRT pQCD+saturation model. High-$p_T$ spectra are obtained from pQCD jet calculation including the energy loss of the parton in the matter prior to its fragmentation to final hadrons.
