Measurement of direct photons in 200{center_dot}A GeV {sup 32}S + Au collisions

Two years ago at the 10th Winter Workshop on Nuclear Dynamics, we reported preliminary results from our measurements of photons in reactions of 200{center_dot}A GeV {sup 32}S ions with Au nuclei. The results had been presented earlier at Quark Matter `93. For central collisions we reported a small, but statistically significant, excess of photons over those that can be accounted for by the two-photon decay branches of neutral pions and eta mesons and by the small photon contributions from other radiative decays. This paper is, in a sense, a sequel to the 1994 presentation. Here we present the final WA80 single `direct` photon results, and we discuss their implications for various theoretical calculations. 13 refs., 2 figs., 1 tab.
