External Gauge Invariance and Anomaly in BS Vertices and Boundstates
Masako Bando, Masayasu Harada, Taichiro Kugo
A systematic method is given for obtaining consistent approximations to the Schwinger-Dyson(SD) and Bethe-Salpeter(BS) equations which maintain the external gauge invariance. We sh…
Axial Anomaly and Transition Form Factors
Masako Bando, Masayasu Harada
We investigate the properties of the amplitude induced by the anomaly. In a relatively high energy region those amplitudes are constructed by the vector meson poles and the anomaly…
Interpolating Axial Anomaly Induced Amplitudes
Masako Bando, Masayasu Harada
We propose an interpolating formula for the amplitude induced by the axial anomaly, concentrating on the transition form factor. The QCD corrections to this a…
Low Energy Theorems of Hidden Local Symmetries
Masayasu Harada, Taichiro Kugo, Koichi Yamawaki
We prove to all orders of the loop expansion the low energy theorems of hidden local symmetries in four-dimensional nonlinear sigma models based on the coset space , with …
