主 题:evolution curvature letter
摘 要:In this letter the author points out that in recent WA80 data an apparent slope parameter of Texp≈180 MeV/c must not mean the fireball becoming equilibrated in whole at some temperatures throughout the stages of the *** author also demonstrates that Texp is merely a mean value of the temperatures of various high-energy photon sources,and predicts that for higher colliding energies(200 A GeV)the shape of the measured single-photon spectra would exhibit some concave curvature,which may be used as a probe for diagnosing quark-gluon plasma.
