Abstract：
The production of large-transverse-momentum photons from Quark-Gluon Plasma (QGP) is discussed,and is used to analyze the high multiplicity event found in the Japanese-American Cooperative Emulsion Experiment (JACCEE).The theoretical result turns out to fit the experiment well.Thus the production of large transverse momentum photons provides an experimental signal of the QCD phase transition.
