手征不平衡夸克物质的热力学

Thermodynamics of quark matter with a chiral imbalance

R. L. S. Farias, Dyana C. Duarte, Gastão Krein, Rudnei O. Ramos

摘要:

我们展示了如何重写发散动量积分的计划可以调和的结果与Nambu-Jona-Lasinio模型和最近的晶格结果的手征过渡中存在的手征不平衡的夸克物质。从依赖于介质的正则化动量积分中分离出了pvp真空贡献,使得只剩下依赖于真空量的紫外发散动量积分。该方案适用于其他常用的研究手征不平衡夸克物质的有效模型,它使我们能够确定其难以再现晶格结果的定性特征的原因,并增强其可预测性和在其他应用中的用途。

英文摘要:

We show how a scheme of rewriting a divergent momentum integral can conciliate results obtained with the Nambu--Jona-Lasinio model and recent lattice results for the chiral transition in the presence of a chiral imbalance in quark matter. Purely vacuum contributions are separated from medium-dependent regularized momentum integrals in such a way that one is left with ultraviolet divergent momentum integrals that depend on vacuum quantities only. The scheme is applicable to other commonly used effective models to study quark matter with a chiral imbalance, it allows us to identify the source of their difficulties in reproducing the qualitative features of lattice results, and enhances their predictability and uses in other applications.
