Arbitrary spin representations in de Sitter from dS/CFT with applications to dS supergravity

We present a simple group representation analysis of massive, and particularly partially massless, fields of arbitrary spin in de Sitter spaces of any dimension. The method uses bulk to boundary propagators to relate these fields to Euclidean conformal ones at one dimension lower. These results are then used to revisit an old question: can a consistent de Sitter supergravity be constructed, at least within its intrinsic horizon? (C) 2003 Elsevier Science B.V.
