Provided tools for quantum field theory in curved spacetime involving massive spin-2 fields.

Enhanced understanding of field behavior in de Sitter geometry.

Abstract

We compute the Pauli-Jordan, Hadamard and Feynman propagators for the massive metrical perturbations on de Sitter space. They are expressed both in terms of mode sums and in invariant forms.
