Anomalies, VMD and the Extended NJL model

Summary, in English

We show how the effective action of the Extended Nambu-Jona-Lasinio model (ENJL) can be defined in the presence of anomalies in a way that reproduces the flavour anomaly. This necessarily breaks Vector Meson Dominance (VMD) in the usual sense. The same method can be used to construct other chiral effective theories involving constituent quarks and spin-1 mesons that give the correct flavour anomaly. We also comment on how standard VMD is the root of this problem and those observed by previous authors in implementing VMD in the anomalous sector.
