色香味在有限温度下锁定了奇异物质和奇异性

Color-flavor locked strange matter and strangelets at finite temperature

L. Paulucci, J. E. Horvath

摘要:

由上夸克、下夸克和奇异夸克组成的系统可能是高密度低温下核物质的真实基态。这种奇异的等离子体被称为奇异夸克物质(SQM),如果夸克处于超导状态,即所谓的色味锁定状态,那么它在能量上似乎更有利。这里提出的计算的基础上的MIT袋模型考虑允许的参数表征系统的稳定性散装SQM(所谓的稳定窗口)和奇怪的,小块的SQM,无论是在颜色风味锁定的情况下,有限的温度的影响。我们将这些结果与未成对SQM进行了比较,并简要讨论了它们的一些天体物理意义。同时,还讨论了奇异夸克的电荷问题。动力学屏蔽的影响虽然对于非配对的SQM奇异夸克团很重要,但在考虑所有三种味色夸克之间的配对时并不相关。

英文摘要:

It is possible that a system composed of up, down and strange quarks consists the true ground state of nuclear matter at high densities and low temperatures. This exotic plasma, called strange quark matter (SQM), seems to be even more favorable energetically if quarks are in a superconducting state, the so-called color-flavor locked state. Here are presented calculations made on the basis of the MIT bag model considering the influence of finite temperature on the allowed parameters characterizing the system for stability of bulk SQM (the so-called stability windows) and also for strangelets, small lumps of SQM, both in the color-flavor locking scenario. We compare these results with the unpaired SQM and also briefly discuss some astrophysical implications of them. Also, the issue of strangelet's electric charge is discussed. The effects of dynamical screening, though important for non-paired SQM strangelets, are not relevant when considering pairing among all three flavor and colors of quarks.
