论文摘要
我们研究了夸克，diquark和baryon的色素相互作用，其周围的重子和/或夸克物质。这是通过对风味SU（2）和SU（3）对称情况下的所有可能风味和自旋状态进行分类来完成的。我们发现，尽管Baryon只有一个周围的BARYON具有最低的相互作用能量，但是当周围环境具有三个以上的重子或变成夸克气体时，夸克具有最低的相互作用能量。由于短范围的核子核子相互作用主要由颜色旋转相互作用支配，因此我们的发现表明，与夸克相比，由于较大的排斥能，其他重子的baryon模式受到抑制，因此在密集物质中为夸克比奇类似的夸克模型提供了基础。同时，当考虑到内部相互作用并且物质密度很高时，颜色旋转的相互作用成为主要的相互作用时，diquark成为最低的能量构型，因此将出现在密集的Baryonic和/或Quark物质中。
We study the color-spin interaction energy of a quark, a diquark and a baryon with their surrounding baryons and/or quark matter. This is accomplished by classifying all possible flavor and spin states of the resulting multiquark configuration in both the flavor SU(2) and SU(3) symmetric cases. We find that while the baryon has the lowest interaction energy when there is only a single surrounding baryon, the quark has the lowest interaction energy when the surrounding has more than three baryons or becomes a quark gas. As the short range nucleon-nucleon interactions are dominated by the color-spin interactions, our finding suggests that the baryon modes near other baryons are suppressed due to larger repulsive energy compared to that of a quark and thus provides a quark model basis for the quarkyoniclike phase in dense matter. At the same time, when the internal interactions are taken into account, and the matter density is high so that the color-spin interaction becomes the dominant interaction, the diquark becomes the lowest energy configuration and will thus appear in both the dense baryonic and/or quark matter.
