Amplitudes from anomalous superconformal symmetry
Dmitry Chicherin, Johannes M. Henn, Emery Sokatchev
We initiate a systematic study of the consequences of (super)conformal symmetry of massless scattering amplitudes. The classical symmetry is potentially broken at the quantum level…
Implications of nonplanar dual conformal symmetry
Dmitry Chicherin, Johannes M. Henn, Emery Sokatchev
Recently, Bern et al observed that a certain class of next-to-planar Feynman integrals possess a bonus symmetry that is closely related to dual conformal symmetry. It corresponds t…
Amplitudes from superconformal Ward identities
Dmitry Chicherin, Johannes M. Henn, Emery Sokatchev
We consider finite superamplitudes of N=1 matter, and use superconformal symmetry to derive powerful first-order differential equations for them. Due to on-shell collinear singular…
