The need to renormalize the cosmological constant
We consider the massless, minimally coupled scalar on de Sitter background. Although the 1-loop divergences of the graviton 1PI 2-point function are canceled by the usual Weyl (C2) and Eddington (R2) counterterms, there is still a finite, nonzero contribution to the graviton 1-point function.
