论文摘要
在Polyakov-nambu-Jona-lasinio模型的非局部扩展的背景下,研究了$π^0 $ MESON性质的行为。分析包括$π^0 $质量,有效的$π^0 $ QUARK耦合以及在零和有限温度下的Pion-to-Vacuum Hadronic形式。将数值结果与本地NJL模型中先前进行的计算进行比较。讨论了手性关系的有效性以及解解和手性对称性恢复过渡的特征。
The behavior of $π^0$ meson properties in the presence of a uniform external magnetic field is studied in the context of a nonlocal extension of the Polyakov-Nambu-Jona-Lasinio model. The analysis includes the $π^0$ mass, the effective $π^0$-quark coupling and the pion-to-vacuum hadronic form factors, both at zero and finite temperature. Numerical results are compared with previous calculations carried out within the local NJL model, when available. The validity of chiral relations and the features of deconfinement and chiral symmetry restoration transitions are discussed.
