Description
In this paper, we study the physical effects of deforming the usual Einstein-Hilbert lagrangian with the Goroff-Sagnotti counterterm (the first which is nonvanishing on shell). The related facts that Schwarzschild’s spacetime is not a solution to the corresponding equations of motion and Birkhoff’s theorem is not valid anymore are analyzed and some consequences worked out.
