Abstract

A bstract : We study three-gluon scattering amplitudes in global de Sitter spacetime, in the angular momentum basis of SO (1 , 4) symmetry representations. At the tree level, they are determined by the intertwiner integrals of harmonic one-forms on the three-sphere. We derive a general formula valid for all helicity configurations of incoming and outgoing gluons and express the amplitudes in terms of Wigner 3j symbols.
