Nucleus-nucleus collisions at ultrarelativistic energies

PDF Version Also Available for Download.

Description

Results are presented from 60 and 200 AGeV p, /sup 16/O and /sup 32/S projectiles with C, Cu, Ag and Au nuclei. Energy spectra are measured at zero degrees and transverse energy distributions in the pseudorapidity range from 2.4 to 5.5 are shown. The average transverse energy per participant is found to be almost independent of projectile-target mass. Transverse momentum distributions of inclusive photons and neutral pions at midrapidity were in addition measured with lead glass array. For all target projectile combinations an increase in average p/sub T/ is observed for small values of entropy, which is deduced from the ... continued below

Description

Results are presented from 60 and 200 AGeV p, /sup 16/O and /sup 32/S projectiles with C, Cu, Ag and Au nuclei. Energy spectra are measured at zero degrees and transverse energy distributions in the pseudorapidity range from 2.4 to 5.5 are shown. The average transverse energy per participant is found to be almost independent of projectile-target mass. Transverse momentum distributions of inclusive photons and neutral pions at midrapidity were in addition measured with lead glass array. For all target projectile combinations an increase in average p/sub T/ is observed for small values of entropy, which is deduced from the central multiplicity density. Different from proton induced reactions 200 AGeV /sup 16/O + Au data show a plateau like region at large values of entropy density. 17 refs., 5 figs.
