Abstract
Two years ago at the 10th Winter Workshop on Nuclear Dynamics, we reported preliminary results from our measurements of photons in reactions of 200·A GeV 32S ions with Au nuclei.1 The results had been presented earlier at Quark Matter ’93.2 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 π0 and η 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,3 and we discuss their implications for various theoretical calculations.
