Relationship between Fujikawa’s Method and the Background Field Method for the Scale Anomaly
We show the equivalence between Fujikawa’s method for calculating the scale anomaly and the diagrammatic approach to calculating the effective potential via the background field method, for an O(N) symmetric scalar field theory. Fujikawa’s method leads to a sum of terms, each one superficially in on...
