Abstract: We compute the initial energy density and net baryon number density in 5%most central Pb+Pb collisions at $\sqrt s=5.5$ TeV from pQCD + (final state)saturation, and describe the evolution of the produced system withboost-invariant transversely expanding hydrodynamics. In addition to the totalmultiplicity at midrapidity, we give predictions for the multiplicity ofcharged hadrons, pions, kaons and (anti)protons, for the total transverseenergy and net-baryon number, as well as for the $p T$-spectrum of chargedhadrons, pions and kaons. We also predict the region of applicability ofhydrodynamics by comparing these results with high-$p T$ hadron spectracomputed from pQCD and energy losses.
