One-Loop Renormalization of Cubic Gravity in Six Dimensions

Phys Rev Lett. 2022 Apr 22;128(16):161301. doi: 10.1103/PhysRevLett.128.161301.

Abstract

We present the complete set of universal one-loop beta functions of cubic gravity in six dimensions. The system admits over 8000 distinct fixed points, of which more than 200 are real. Some of them might be relevant for the quantization of gravity in the physical case of four dimensions.
