摘要：

We present calculations of mesonic (quark-antiquark) modes in a generalized Nambu-Jona-Lasinio model with three quark flavours. The effective interaction between quarks is symmetric under chiral SU(3)L⊗ SU(3)R and incorporates a U(1)A-breaking six-point interaction as suggested by 't Hooft. We concentrate on the evaluation of masses and decay constants of pseudoscalar mesons, with special emphasis on the underlying symmetry breaking patterns. Scalar, vector and axial vector mesonic modes are also discussed. © 1990.
