Description
Based on [2105.12742, 2303.07391] and upcoming work, I will discuss various aspects of the renormalization of scalar effective field theory (EFT). For single insertions of EFT operators, we computed anomalous dimensions at five loop order and high mass dimension using the R* method. For multiple insertions, we present three-loop results and a general non-renormalization theorem that dictates many zeros in the anomalous dimensions. Further zeros are found in the basis of conformal primaries, which I will motivate as a preferred type of basis to expose the structure of anomalous dimensions. Finally, I will discuss how these methods and results extend to other theories, such as the Standard Model EFT.
