摘要

利用nambujna - lasinio模型研究了在考虑真空效应导致手性对称性破缺的情况下，夸克物质中存在导致夸克自旋极化相的伪矢量型夸克-反夸克凝聚相的可能性。此外，还研究了伪矢量型夸克-反夸克凝聚和张量型夸克-反夸克凝聚上可能存在的nambugoldstone模，这些模也会导致夸克自旋极化相。

A possibility of existence of a pseudovector-type quark-antiquark condensate in the quark matter and Nambu-Goldstone modes on that condensate in the Nambu-Jona-Lasinio model

A possibility of a pseudovector-type quark-antiquark condensed phase, which leads to a quark spin polarized phase, in the quark matter is investigated taking account of the vacuum effects leading to the chiral symmetry breaking by using the Nambu-Jona-Lasinio model. Also, possible Nambu-Goldstone modes on the pseudovector-type quark-antiquark condensate and the tensor-type quark-antiquark condensate, which also leads to the quark spin polarized phase, are investigated.
