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, effective approach, and gravitational potential
Riccardo Fecchio, Ilya L. Shapiro
We explore and discuss corrections to the Newton potential from the quantum effects of conformal matter fields. In this special case, one can compare different approaches, includin…
