夸克-胶子等离子体状态方程的修正Bag模型

Modified Bag Models for the Quark Gluon Plasma Equation of State

V. V. Begun, M. I. Gorenstein, O. A. Mogilevsky

摘要:

考虑了袋模型状态方程(EoS)的修正形式。它们的构造满足在格点量子色动力学计算中观察到的夸克-胶子等离子体EoS的主要定性特征。在SU(3)胶子动力学和全QCD中,与高温T下的格点结果作了定量比较。我们的分析主张袋常数B为负值。

英文摘要:

The modified versions of the bag model equation of state (EoS) are considered. They are constructed to satisfy the main qualitative features observed for the quark-gluon plasma EoS in the lattice QCD calculations. A quantitative comparison with the lattice results at high temperatures T are done in the SU(3) gluodynamics and in the full QCD with dynamical quarks. Our analysis advocates a negative value of the bag constant B.
