Description
Computing the anomalous dimensions of local composite operators present in both renormalisable and non-renormalisable QFTs is generally challenging due to the presence of many scales and loops. In this talk we present an extension of the local R* method which fully automates this task. By extending the local R* operation to arbitrary QFTs we, transform this problem to one of computing massless propagator integrals, suitable for efficient evaluation with the Forcer program.
