Finite Callan-Symanzik renormalisation for multiple scalar fields
May 1, 2023
We study a finite, divergence-free approach to renormalisation originally proposed in the early '70s by Blaer and Young, and Callan. It is based on equations similar to the Callan-Symanzik equations and introduced in the context of the & lambda;& phi;4 theory. We generalise this method to the case of two interacting scalar fields, with obvious generalisation to an arbitrary number of fields.& COPY; 2023 The Author(s). Published by Elsevier B.V.
