Multiplicity and pseudorapidity distribution of photons in S+Au reaction at 200A GeV
1998
The photon multiplicity has been measured for the first time in S+Au collisions at 200A GeV over a wide pseudorapidity range (2.8{le}{eta}{le}5.2) employing a fine granularity preshower detector. The pseudorapidity density of photons increases with centrality, reaching {approximately}200 at the highest centrality studied. The results are compared with measurements of the charged particle multiplicity and with predictions of the VENUS event generator. {copyright} {ital 1998} {ital The American Physical Society}
