摘要: 本文讨论了用高能光子诊断夸克胶子等离子体研究中的不确定性问题，基于局部热平衡假设，对比研究新近的有关文献，发现对来自极端相对论性重离子碰撞的高能光子，仍可以从不确定性中找到某些确定的特性．我们建议实验上测得的高能光子总谱的形状可以用作为诊断夸克胶子等离子体是否存在的手段． 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 ...
