Spinor-helicity formalism for massless fields in AdS4. Part II. Potentials
Balakrishnan Nagaraj, Dmitry Ponomarev
Abstract
A bstract 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. This analysis illustrates a typical computation of an amplitude without internal lines in our formalism.
