HADRON PHYSICS WITH CERES - SPECTRA AND COLLECTIVE FLOW

Hadronic spectra from interactions of Pb on Au at 158 AGeV/c have been measured by the CERES experiment at the CERN SPS. We report on prelim inary results on transverse mass spectra of identified pions and negat ive hadrons as well as spectra of the positive charge excess obtained by subtracting the negative particle distribution from that of positiv e tracks. We have also performed a study of the event azimuthal anisot ropies which give evidence for directed and elliptic flow in non-centr al collisions.
