Further Evidence for a Gravitational Fixed Point
arXiv:hep-th/0511177 · doi:10.1103/PhysRevD.73.041501
Abstract
A theory of gravity with a generic action functional and minimally coupled to N matter fields has a nontrivial fixed point in the leading large N approximation. At this fixed point, the cosmological constant and Newton's constant are nonzero and UV relevant; the curvature squared terms are asymptotically free with marginal behaviour; all higher order terms are irrelevant and can be set to zero by a suitable choice of cutoff function.
