Query: A Second Look at Single Photon Production in S+Au Collisions at 200
  A$\cdot$GeV and Implications for Quark Hadron Phase Transition   We reanalyze the production of single photons in S+Au collisions at CERN SPS
to investigate: i) the consequences of using a much richer equation of state
for hadrons than the one used in an earlier study by us; and, ii) to see if the
recent estimates of photon production in quark-matter (at two loop level) by
Aurenche et al. are consistent with the upper limit of the photon production
measured by the WA80 experiment. We find that the measured upper limit is
consistent with a quark hadron phase transition. The measured upper limit is
also consistent with a scenario where no phase transition takes place, but
where the hadronic matter reaches a density of several hadrons per unit volume;
which is rather unphysical.
