Abstract

Transverse energy, charged particle pseudorapidity distributions and photon transverse momentum spectra have been studied as a function of the number of participants (Npart) and the number of binary nucleon-nucleon collisions (Ncoll) in 158·A GeV Pb+Pb collisions over a wide impact parameter range. A scaling of the transverse energy pseudorapidity density at midrapidity as ∼ N1.08±0.06 part and ∼ N0.83±0.05 coll is observed. For the charged particle pseudorapidity density at midrapidity we find a scaling as ∼ N1.07±0.04 part and ∼ N0.82±0.03 coll. This faster than linear scaling with Npart indicates a violation of the naive Wounded Nucleon Model.

N2 - Transverse energy, charged particle pseudorapidity distributions and photon transverse momentum spectra have been studied as a function of the number of participants (Npart) and the number of binary nucleon-nucleon collisions (Ncoll) in 158·A GeV Pb+Pb collisions over a wide impact parameter range. A scaling of the transverse energy pseudorapidity density at midrapidity as ∼ N1.08±0.06 part and ∼ N0.83±0.05 coll is observed. For the charged particle pseudorapidity density at midrapidity we find a scaling as ∼ N1.07±0.04 part and ∼ N0.82±0.03 coll. This faster than linear scaling with Npart indicates a violation of the naive Wounded Nucleon Model.
