摘要：

An effective lagrangian which simultaneously describes interactions of scalar, pseudoscalar, vector and axial-vector mesons as well as diquarks including meson and diquark mixing effects is obtained from an extended QCD-motivated Nambu-Jona-Lasinio model. Estimates for the diquark masses are given.
