Abstract

It is known that the graviton two-point function for the de Sitter invariant 'Euclidean' vacuum in a physical gauge grows logarithmically with distance in spatially flat de Sitter spacetime. We show that this logarithmic behaviour is a gauge artefact by explicitly demonstrating that the same behaviour can be reproduced by a pure-gauge two-point function.
