Conformal anomaly in a vector field model with auxiliary scalar field
Samuel W. P. Oliveira, Públio Rwany B. R. do Vale, Ilya L. Shapiro
The conformal anomaly has well-known ambiguities related to the possible schemes of regularization and renormalization. In case of dimensional regularization, one of the options is…

Trace anomaly for a conformal 2D vector field model
Samuel W. P. Oliveira, Ilya L. Shapiro
The trace anomaly and anomaly-induced action are evaluated for the two-dimensional vector theory with classical conformal symmetry. Implementing local conformal symmetry while…
