✦ Synopsis

The centrality dependence of the charged multiplicity, transverse energy, and elliptic flow coefficient is studied in a hydrodynamic model, using a variety of different initializations which model the initial energy or entropy production process as a hard or soft process, respectively. While the charged multiplicity depends strongly on the chosen initialization, the p T -integrated elliptic flow for charged particles as a function of charged particle multiplicity and the p T -differential elliptic flow for charged particles in minimum bias events turn out to be almost independent of the initial energy density profile.

We compute the particle multiplicities and transverse energies at central and nearly central AA collisions at RHIC and LHC. The initial state is computed from perturbative QCD supplemented by the conjecture of saturation of produced partons. The expansion stage is described in terms of hydrodynamics

Antiproton production in 11.7 A.GeV/c Au+Au collisions over a wide transverse-mass coverage was studied in the AGS-E866. The inverse slope parameter increases rapidly as a function of centrality. Antiproton yields in Si+A and Au+Au collisions are consistent with
