On the new way of symmetry breaking in scalar QED and the one-loop renormalization
Lucas Ducastelo de C. C. Lima, Ilya L. Shapiro
It is well known that single real scalar field does not allow gauge coupling to the Abelian vector field. Using the complex scalar model as a starting point, we construct the Abeli…
Local conformal symmetry and anomalies with antisymmetric tensor field
Ilya L. Shapiro
We consider the trace anomaly, which results from the integration of the massless conformal fermion field with the background of metric and antisymmetric tensor fields. The non-loc…
Antisymmetric Tensor Field and Cheshire Cat Smile of the Local Conformal Symmetry
Ilya L. Shapiro
The conformal version of the antisymmetric second-order tensor field in four spacetime dimensions does not have gauge invariance extensively discussed in the literature for more th…
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…
