The Extended Chiral Bosonisation And Pion-Diquark Effective Action

We consider bosonisation of the low-energy QCD based on integrating the anomaly of the extended chiral (E$\chi$) transformation which depends both on pseudoscalar meson and scalar diquark fields as parameters. The relationship between extended chiral and usual chiral anomalies and related anomalous actions is studied. The effective action for the extended chiral field $\U$ depending on complete set of anomalous generators of the E$\chi$-transformation is given. The terms of this effective action relevant to interaction of pions and $\bar 3_c$ scalar diquarks are written down explicitly.
