Abstract
More uncertainties in the studies about diagnosing Quark-gluon plasma (QGP) by use of high-energy photon are discussed upon the assumption of local thermal equilibrium as well as a comparison study for recent literature, it is found that some definite aspects of high-energy photons originating from ultra-reletivistic heavy-ion collision may be still extracted from the uncertainties. We suggest that the shape of the measurable overall inclusive transverse momentum spectre for high-energy photons may be ...
