dS_4 metamorphosis

Abstract
We study quantum properties of Euclidean gravity with Lambda>0. We focus on theories with very structured particle spectra, and compute a variety of loop contributions. In the case of infinite towers of such spectra (both bosonic and fermionic), many cancellations are observed, effectively yielding a lower dimensional expression.
