论文摘要
我们在有限温度下在线性sigma模型的框架中研究了外部任意磁场的中性锥质量。这样，我们已经计算了锥度自能源，通过重新点燃构建了分散方程，并以零三动量极限求解了分散关系。在计算Pion质量时，我们包括Meson自耦合的热和磁性贡献以及近似手性订单参数$ v_0 $。我们报告$π^0 $质量随磁场而减小，并且随温度而增加。
We study the neutral pion mass in the presence of an external arbitrary magnetic field in the framework of the linear sigma model coupled to quark (LSMq) at finite temperature. In doing so, we have calculated the pion self-energy, constructed the dispersion equation via re-summation, and solved the dispersion relation at zero three momentum limit. In calculating the pion mass, we have included meson self-coupling's thermal and magnetic contribution and approximate chiral order parameter $v_0$. We report that the $π^0$ mass decreases with the magnetic field and increases with temperature.
