Scattering of quantum particles in global de Sitter spacetime II: Scalars in deep infrared
We apply the S-matrix formalism developed in Part I to the interacting scalar theory in four-dimensional de Sitter spacetime. The amplitudes are computed in the angular momentum basis, appropriate to the representations of SO(1, 4) de Sitter symmetry group. We discuss the properties of wavefunctions...
