论文摘要
在Pauli-Villars正规化的PNJL模型中研究了夸克异常磁矩（AMM）对磁场下手性恢复和解料相变的影响。将夸克异常磁矩的线性$ b $项引入了我们模型的拉格朗日密度，并且它扮演着反向催化与相变的作用。使用固定磁场，临界温度随夸克AMM降低。固定夸克AMM时，对于小夸克AMM而言，临界温度会随着磁场而增加，但是大夸克弹药会随着磁场而降低。手性恢复和解解相变的临界温度取决于两个竞争因素，磁场的催化作用和夸克异常磁矩的反催化。
The effect of quark anomalous magnetic moment (AMM) to chiral restoration and deconfinement phase transitions under magnetic fields is investigated in a Pauli-Villars regularized PNJL model. A linear-in-$B$ term for quark anomalous magnetic moment is introduced to the Lagrangian density of our model, and it plays the role of inverse catalysis to the phase transitions. With fixed magnetic field, the critical temperature decreases with quark AMM. When fixing quark AMM, the critical temperature increases with magnetic field for a small quark AMM, but decreases with magnetic field for a large quark AMM. The critical temperature of chiral restoration and deconfinement phase transitions is determined by the two competing factors, the catalysis effect of magnetic field and inverse catalysis of quark anomalous magnetic moment.
