论文摘要
张量冷凝物的可能形成起源于夸克之间的张量相互作用，在包括kobayashi-maskawa-nof-hooft互动的三种风味nambu-jona-lasinio模型中，导致风味混合。结果表明，出现了独立的两种张量冷凝物，与与光夸克相关的混合相比，通过风味混合的效果，与奇怪的夸克相关的张量很容易发生。同样，还表明，由于风味混合效果，如果包括Kobayashi-Maskawa-'t Hooff的相互作用，则与奇怪的夸克相关的张量凝聚物出现在稍小的化学势中。还表明，由于风味混合，两种张量冷凝物可能在某些夸克化学势中共存。
The possible formation of tensor condensates originated from a tensor-type interaction between quarks is investigated in the three-flavor Nambu-Jona-Lasinio model including the Kobayashi-Maskawa-'t Hooft interaction, which leads to flavor mixing. It is shown that independent two tensor condensates appear and a tensor condensate related to the strange quark easily occurs by the effect of the flavor mixing compared with one related to light quarks. Also, it is shown that the tensor condensate related to the strange quark appears at a slightly smaller chemical potential if the Kobayashi-Maskawa-'t Hooft interaction is included, due to the flavor mixing effect. It is also shown that the two kinds of tensor condensates may coexist in a certain quark chemical potential due to the flavor mixing.
