OSTI ID:5612147
The following comparison of E-802 Si + Au spectra and RQMD predictions is based on the 802 data from November 1987, published in Refs. 2 and 3, and the RQMD calculations described in Refs. 4 and 5. The data presented here often have been binned differently compared to Refs. 1, 2 to facilitate the comparison with the theoretical data. The systematic errors are estimated as less than {plus minus}20%. The RQMD data consists of listings of 203 complete events, all with an incident kinetic energy T=14.5*28 GeV and an impact parameter of b=1 fm. The output listings contain 4-vectors of all outgoing particles, and have been sorted into spectra of invariant cross section (normalized per event) versus transverse mass for definite rapidity bins, in the same way as the data. It has been assumed that the RQMD output obeys Poisson statistics. The RQMD data differ from the experiment in two important ways. The experiment was triggered on high overall charged multiplicity and therefore contains events with a distribution over central impact parameters, whereas the theory uses but one impact parameter (1 fm). The incident momentum in the experiment was {rho}{sub 802} = 28*14.6 GeV/c, while the RQMD calculation used {rho}{sub QMD} = 15.4*28 GeV/c, i.e. a difference of 22.4 GeV/c, or 5%.
