Structure of two-loop SMEFT anomalous dimensions via on-shell methods
Zvi Bern, Julio Parra-Martinez, Eric Sawyer
We describe on-shell methods for computing one- and two-loop anomalous dimensions in the context of effective field theories containing higher-dimension operators. We also summariz…

Non-renormalization and operator mixing via on-shell methods
Zvi Bern, Julio Parra-Martinez, Eric Sawyer
Using on-shell methods, we present a new perturbative non-renormalization theorem for operator mixing in massless four-dimensional quantum field theories. By examining how unitarit…
