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…

On the renormalization of massive vector field theory coupled to scalar in curved space-time
Ioseph L. Buchbinder, Públio Rwany B. R. do Vale, Guilherme Y. Oyadomari +1
We consider the renormalization of massive vector field interacting with charged scalar field in curved spacetime. Starting with the theory minimally coupled to external gravity an…
