热磁化夸克物质中中性介子的性质:尺寸依赖效应

高能物理 - 唯象学 2022-03-18 v2

摘要

本文在Nambu–Jona-Lasinio模型框架下,研究了热介质中中性介子性质的有限尺寸与热磁联合效应。具体而言,通过使用平均场近似和环面拓扑下具有反周期边界条件的Schwinger本征时间方法,我们评估了在手征相变、组分夸克质量以及介子观测量(如π0\pi ^0σ\sigma介子质量及π介子衰变常数)随尺寸、温度、化学势和外磁场强度变化的情况。结果表明,这些观测量受到相关变量联合效应的强烈影响,最终结果取决于这些竞争现象的平衡。

15 pages; 18 figures. In the second version of the manuscript, we have obtained results with both periodic and antiperiodic boundary conditions; a new Subsection (III.A) has been included with a discussion of the behavior of the critical coupling constant concerning the different boundary conditions; the physical discussion of the results has been enriched
