Thermalization and Flow in 158 AGeV Pb+Pb Collisions

The WA98 experiment at the CERN SPS measures Pb+Pb Collisions at 158 AGeV. The scaling properties of the charged particle multiplicity at midrapidity with the number of participants are studied using the SPMD and the MIRAC detector. Neutral pion spectra obtained from the LEDA detector are compared to hydrodynamical parametrizations. The collective flow in the target fragmentation region has been studied using the Plastic Ball detector. The results exhibit a strong dependence on centrality and rapidity.

Directed and Elliptic Flow in 158 AGeV Pb+Pb Collisions

Directed and elliptic flow of protons and positively charged pions has been studied in the target fragmentation region using the Plastic Ball detector in the WA98 experiment. The results exhibit a strong dependence on centrality, rapidity, and transverse momentum. The rapidity dependence can be described by a Gaussian distribution. The model comparisons reveal a large discrepancy of the flow strength obtained from the data and the simulations.
