DESCRIPTION;ENCODING=QUOTED-PRINTABLE: Title: All-Plus QED Wavefunctions in de Sitter Space=0D=0A=
=0D=0A=
Abstract: I will discuss tree-level wavefunction coefficients in scalar QED in four-dimensional de Sitter space, focusing on a charged scalar pair coupled to an arbitrary number of positive-helicity photons. We find a remarkably simple all-multiplicity structure for these coefficients. I will present the resulting compact formula and explain how its analytic structure, Abelian Ward identities, and conformal symmetry lead to an exact recursion.
