Massive Bosons and the dS/CFT correspondence
arXiv:hep-th/0208229 · doi:10.1103/PhysRevD.67.084015
Abstract
We compute the boundary two point functions of operators corresponding to massive spin 1 and spin 2 de Sitter fields, by an extension of the ``S-Matrix'' approach developed for bulk scalars. In each case the two point functions are of the form required for conformal invariance of the dual boundary field theory. We emphasise that in the context of dS/CFT one should consider unitary representations of the Euclidean conformal group, without reference to analytic continuation of the boundary theory to Lorentzian signature.
