Renormalization Ambiguities and Conformal Anomaly in Metric-Scalar Backgrounds
M. Asorey, G. de Berredo-Peixoto, I. L. Shapiro
We analyze the problem of the existing ambiguities in the conformal anomaly in theories with external scalar field in curved backgrounds. In particular, we consider the anomaly of…
