Functional Dimensional Regularization for O(N) Models
P. Beretta, A. Codello
The novel functional dimensional regularization (FDR) scheme has proven capable of yielding results that are competitive with the state-of-the-art in the computation of critical ex…

Rethinking Dimensional Regularization in Critical Phenomena
P. Beretta, A. Codello
We show that it is possible to use dimensional regularization (DR) beyond the usual -expansion in the context of renormalization group (RG) calculations in Critical Ph…
