| contents | We calculate Euclidean correlation functions through next-to-leading order in the low energy effective theory of gravity. We focus on correlation functions of curvature and volume operators, calculating these functions through one-loop order. We show that quantum fluctuations of the background spacetime must be taken into account in order to obtain gauge invariant expressions, and we point out a subtlety associated with the analytic continuation of the conformal mode. Our final expressions for the correlation functions involve only Newton's constant and the source-sink separation, and they are a universal prediction of the low energy effective theory. Thus, they serve as a useful point of comparison for nonperturbative lattice formulations of gravity. |
