Anomalous Ward identities for on-shell amplitudes at the conformal fixed point
Dmitry Chicherin, Johannes Henn, Simone Zoia
Conformal symmetry underlies many massless quantum field theories, but little is known about the consequences of this powerful symmetry for on-shell scattering amplitudes. Working…
Pentagon Wilson loop with Lagrangian insertion at two loops in super Yang-Mills theory
Dmitry Chicherin, Johannes Henn
We compute the two-loop result for the null pentagonal Wilson loop with a Lagrangian insertion (normalized by the Wilson loop without insertion) in planar, maximally supersymmetric…
The SAGEX Review on Scattering Amplitudes, Chapter 9: Integrability of Amplitudes in Fishnet Theories
Dmitry Chicherin, Gregory P. Korchemsky
We discuss the properties of scattering amplitudes in a conformal bi-scalar fishnet theory that previously appeared in the study of integrable deformations of SYM. I…
The SAGEX Review on Scattering Amplitudes
Gabriele Travaglini, Andreas Brandhuber, Patrick Dorey +35
This is an introduction to, and invitation to read, a series of review articles on scattering amplitudes in gauge theory, gravity, and superstring theory. Our aim is to provide an…
Symmetry properties of Wilson loops with a Lagrangian insertion
Dmitry Chicherin, Johannes M. Henn
Null Wilson loops in super Yang-Mills are dual to planar scattering amplitudes. This duality implies hidden symmetries for both objects. We consider closely related…
