Aspects of Anomalies in Field Theory

  title={Aspects of Anomalies in Field Theory},
  author={Kazuo Fujikawa},
We discuss some formal aspects of quantum anomalies with an emphasis on the regularization of field theory. We briefly review how ambiguities in perturbation theory have been resolved by various regularization schemes. To single out the true quantum anomaly among ambiguities, the combined ideas of PCAC, soft pion limit and renormalizability were essential… CONTINUE READING
