Cancelling the U(1) Anomaly in the S-matrix of N=4 Supergravity
Zvi Bern, Julio Parra-Martinez, Radu Roiban
supergravity is understood to contain a anomaly which manifests itself via the nonvanishing of loop-level scattering amplitudes that violate a tree-level char…

Curvature-Squared Multiplets, Evanescent Effects and the U(1) Anomaly in N = 4 Supergravity
Zvi Bern, Alex Edison, David Kosower +1
We evaluate one-loop amplitudes of N = 4 supergravity in D dimensions using the double-copy procedure that expresses gravity integrands in terms of corresponding ones in Yang--Mill…

Manifesting enhanced cancellations in supergravity: integrands versus integrals
Zvi Bern, Michael Enciso, Julio Parra-Martinez +1
Examples of "enhanced ultraviolet cancellations" with no known standard-symmetry explanation have been found in a variety of supergravity theories. By examining one- and two-loop e…
