Abstract :
We present the first analysis of preliminary data for Pb + Pb at 160 AGeV using 3 + 1-dimensional relativistic hydrodynamics. We find excellent agreement with the rapidity spectra of negative hadrons and protons and the correlation measurements. The data indicate a large amount of stopping; 65% of the invariant energy of the collision is thermalized and 73% of the baryons are contained in the central fireball. Within our model this implies that a quark-gluon-plasma of lifetime 3.4 fm/c was formed.
