Abstract

In the search for the quark-gluon plasma at CERN SPS, several signals wereobserved suggesting that this new state of matter was actually produced inthe interactions induced by the lead beam at 158A GeV. The transverse flowphenomena characterize the distribution of the particles in the final state of the collision, and are expected to provide some indications about the initial state. More precisely the existence of an elliptic flow directed along the reaction plane in the case of the non central collisions of two spherical nuclei, has been proposed to probe the thermalisation of the initialstate. Indeed. the NA50 collaboration has measured these kind of effects in Pb-Pb collisions at 158A GeV, and we can conclude that the thermalisationof the initial state is actually present in these interactions. Conversely. there is no evidence for such a thermalisation in the NA38 data which were obtained with the sulphur beam at 200A GeV, neither in S-S nor in S-Cu interactions.
