本文给出了中性和β平衡稠密双味夸克物质中胶子和光子的德拜和迈斯纳屏蔽质量的计算结果。在正常相和理想双色超导相的极限范围内，屏蔽质量与已知结果一致。最有趣的是，我们发现迈斯纳屏蔽质量的平方可以是负的，这表明在致密的夸克物质中存在等离子体型的色磁不稳定性。
The results for the Debye and Meissner screening masses of the gluons and the photon in the case of neutral and {beta}-equilibrated dense two-flavor quark matter are presented. In the limits of the normal phase and the ideal two-flavor color superconducting phase, the screening masses coincide with the known results. Most interestingly, we find that the Meissner screening masses squared can be negative, indicating a plasma-type chromomagnetic instability in dense quark matter.
