论文摘要

在这项工作中,在背景磁场的存在比QCD的能量标度更强的情况下研究了带电旋转的质量。我们在狄拉克方程中引入了一个异常的磁动量项,并获得夸克传播器。我们发现了一个新颖的有限兰道级,称为$ tl $ ll,成为占主导地位,而不是传统的最低兰道级。我们检查的是,由于Landau水平的变化,它的质量下降了$ \ sim \ sim 0.8〜 \ mathrm {gev}^2 $,用于充电pions及其质量在Ultra-Strong磁场上极大地限制为中性一个,$ eb \ sim 1.6〜 \ sim 1.6〜 \ mathrm {gevev}^2 $ sim latte是一致的。

In this work, the mass of charged pions is investigated in the presence of background magnetic fields stronger than the energy scale of QCD. We introduce an anomaly magnetic momentum term in the Dirac equation and obtain the quark propagator as consequence. We find a novel finite Landau level, denoted as $tl$LL, becoming dominant rather than the conventional lowest Landau level. We examine that, due to the shifting of Landau level, it drives a mass decreasing around $eB\sim 0.8~\mathrm{GeV}^2$ for charged pions and their masses drastically limit to the neutral one at ultra-strong magnetic field, $eB\sim 1.6~\mathrm{GeV}^2$, which is consistent with the recent lattice simulation.
