Higher Derivative Gravity and Asymptotic Safety in Diverse Dimensions

Ohta, Nobuyoshi, Percacci, Roberto

Understand

We derive the one-loop beta functions for a theory of gravity with generic action containing up to four derivatives.

  • The calculation is done in arbitrary dimension and on an arbitrary background.
  • The special cases of three, four, near four, five and six dimensions are discussed in some detail.
  • We find that the theories have nontrivial UV fixed points and are asymptotically safe in all dimensions we study.
