非局部Polyakov-Nambu-Jona-Lasinio模型的推广及其应用

Extensions and further applications of the nonlocal Polyakov--Nambu--Jona-Lasinio model

Thomas Hell, Kouji Kashiwa, Wolfram Weise

摘要:

通过在夸克准粒子传播子中引入动量相关的波函数重整化,进一步改进了非定域Polyakov圈扩展的Nambu-Jona-Lasinio(PNJL)模型.两个和三个版本的改进PNJL模型进行了讨论,后者包括(非局部)的't Hooft-Kobayashi-Maskawa行列式相互作用,以考虑轴向U(1)异常。热力学和相位的研究和最近的晶格QCD结果进行了比较。

英文摘要:

The nonlocal Polyakov-loop-extended Nambu--Jona-Lasinio (PNJL) model is further improved by including momentum-dependent wave-function renormalization in the quark quasiparticle propagator. Both two- and three-flavor versions of this improved PNJL model are discussed, the latter with inclusion of the (nonlocal) 't Hooft-Kobayashi-Maskawa determinant interaction in order to account for the axial U(1) anomaly. Thermodynamics and phases are investigated and compared with recent lattice-QCD results.
