An effective Lagrangian with no U(1) problem in CP$^{n-1}$ models and QCD
The author writes an effective lagrangian which gives two-point Green's functions satisfying the anomalous Ward identities for the U (1) axial vector current with a singlet particle that has a non- vanishing mass in the chiral limit. It is shown that the mechanism that has been postulated by Wi...
