摘要:

本文评述了四维QCD广义Nambu-Jona-Lasinio模型的各个方面。详细讨论了介子激发的性质,特别注意手征π介子。从微观上描述了真空中自发的手征对称性破缺和高激发态介子和重子谱中的有效手征对称性恢复。

英文摘要:

Various aspects of the Generalised Nambu-Jona-Lasinio model for QCD in four dimensions are reviewed. The properties of mesonic excitations are discussed in detail, with special attention paid to the chiral pion. The spontaneous chiral symmetry breaking in the vacuum and the effective chiral symmetry restoration in the spectrum of highly excited mesons and baryons are described microscopically.
