摘要：

We report the continuum limits of the speed of sound, C-s, and the specific heat at constant volume, C-V, in quenched QCD at temperatures of 2T(c) and 3T(c). At these temperatures, C-s is within 2-sigma of the ideal gas value, whereas C-V differs significantly from the ideal gas. However, both are compatible with results expected in a theory with conformal symmetry. We investigate effective measures of conformal symmetry in the high temperature phase of QCD.
