标题： The speed of sound and specific heat in the QCD plasma: hydrodynamics, fluctuations and conformal symmetry

摘要： 我们报告了淬火QCD在2Tc和3Tc温度下的声速c_s和定容比热c_v的连续极限。 在这些温度下，c_s与理想气体值在2-sigma范围内一致，而c_v与理想气体有显著差异。 然而，两者都与具有共形对称性的理论预期结果相容。 我们研究了QCD高温相中有效测量共形对称性的方法。 显示英文摘要

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 2Tc and 3Tc. 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.
