Mathematical feature of photon spectra produced in ultra-relativistic heavy-ion collision
Description
In 1994 the first single-photon spectra from the 200 GeV/A S + Au collisions at CERN SPS were reported by WA80 group. Based on these data, it can be proved that as long as there is an instantaneous thermal distribution T(r, t) in an expanding fireball at each instant, the basic mathematical feature of various kinds of photon spectra is that photon yield is approximately an exponential function of the transverse momentum PT in some region, which is basically irrelevant to the uncertainties enclosed in the theoretical estimations
