  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.
