Weyl-Weyl Correlator in de Donder Gauge on de Sitter

Published 20 May 2012 in gr-qc and hep-th | (1205.4466v1)

Abstract: We compute the linearized Weyl-Weyl correlator using a new solution for the graviton propagator on de Sitter background in de Donder gauge. The result agrees exactly with a previous computation in a noncovariant gauge. We also use dimensional regularization to compute the one loop expectation value of the square of the Weyl tensor.
