We report on a systematic study of midrapidity transverse energy production and forward energy flow in interactions of 160 and 32S projectiles with S, Cu, Ag and Au targets at 60 and 200 GeV/nucleon. The vari- ation of the shape of the Er distributions with target and projectile mass can be understood from collision geometry. Average Er values determined for central col- lisions show an increasing stopping power for heavier target nuclei.

The vari- ation of the shape of the Er distributions with target and projectile mass can be understood from collision geometry. Average Er values determined for central col- lisions show an increasing stopping power for heavier target nuclei. A higher relative stopping is observed at 60 GeV/nucleon than at 200 GeV/nucleon. Bjorken esti- mates of the energy density reach approximately 3 GeV/fm3 in high Er events at 200 GeV/nucleon with 160 and 32Sprojectiles. The systematics of the data and the shapes of Er and pseudorapidity distributions are well described by the Lund model Fritiof.» weiterlesen» einklappen
