Abstract: | We discuss a previously proposed renormalizable theory of gravity involving R2μν, and N massless fermion (vector boson) fields in which the unitarity problem is resolved within a expansion. The infrared limit is precisely Einstein's theory, but the high-energy behavior is determined by the dimensionless, asymptotically free coupling of the R2μν. Various attractive possible consequences of the theory are pointed out. |
