M. Bluhm, B. Kampfer, R. Schulze, D. Seipt

摘要:

在唯象准粒子模型下,讨论了QCD状态方程对夸克质量和温度的依赖性,并与格点量子色动力学的结果进行了比较。准粒子色散关系采用不同的近似,与夸克质量和解除禁闭温度的状态方程的标度性质进行了研究和渐近大温度的延续。

英文摘要:

Within a phenomenological quasiparticle model, the quark mass and temperature dependence of the QCD equation of state is discussed and compared with lattice QCD results. Different approximations for the quasiparticle dispersion relations are employed, scaling properties of the equation of state with quark mass and deconfinement temperature are investigated and a continuation to asymptotically large temperatures is presented.
