Spinor-Helicity Formalism for Massless Fields in AdS$_4$ II: Potentials

Understand

In a recent letter we suggested a natural generalization of the flat-space spinor-helicity formalism in four dimensions to anti-de Sitter space.

• In the present paper we give some technical details that were left implicit previously.
• For lower-spin fields we also derive potentials associated with the previously found plane wave solutions for field strengths.
• We then employ these potentials to evaluate some three-point amplitudes.
