论文摘要

我们通过计算Polyakov回路的波动来研究有限磁场对重夸克的反馈相变的影响。证明明确的Z(3)断裂场随磁场而增加,从而导致(伪)临界温度降低,并且相图中的一阶区域缩小。给出了捕获Z(3)破裂场在强和弱磁场上的Z(3)破裂场的行为的现象学方程,并给出了大规模和无质量的夸克。最后,我们探讨了动态光夸克的情况,并证明了改进的成分夸克质量功能如何在有效模型中强制执行反封码温度的正确磁场依赖性,如晶格QCD计算中所观察到的那样。

We study the impact of a finite magnetic field on the deconfinement phase transition for heavy quarks by computing the fluctuations of the Polyakov loops. It is demonstrated that the explicit Z(3) breaking field increases with the magnetic field, leading to a decrease in the (pseudo) critical temperatures and a shrinking first-order region in the phase diagram. Phenomenological equations that capture the behaviors of the Z(3) breaking field at strong and weak magnetic fields for massive and massless quarks are given. Lastly, we explore the case of dynamical light quarks and demonstrate how an improved constituent quark mass function can enforce the correct magnetic field dependence of the deconfinement temperature in an effective model, as observed in Lattice QCD calculations.
