[HTML][HTML] Heat kernel coefficients for massive gravity

R Ferrero, MB Fröb, WCC Lima - Journal of Mathematical Physics, 2024‏ - pubs.aip.org
We compute the heat kernel coefficients that are needed for the regularization and
renormalization of massive gravity. Starting from the Stueckelberg action for massive gravity …

We study the strong-field limit of a theory involving a quantum scalar field coupled to a vector
background, which can be either an electromagnetic field or a non-gauge field coupled …
