Spinor-helicity formalism for massless fields in AdS4 III: contact four-point amplitudes
Balakrishnan Nagaraj, Dmitry Ponomarev
Abstract
A bstract We study contact four-point amplitudes in the spinor-helicity formalism in anti-de Sitter space. We find that these amplitudes can be brought to an especially simple form, which we call canonical. Next, we classify consistent contact amplitudes by requiring correct transformation properties with respect to the AdS isometry algebra. Finally, we establish a connection between the canonical form of AdS amplitudes and scalar multi-trace conformal primaries in flat space.
