A note on causality constraining higher curvature corrections to gravity

A. Gruzinov, M. Kleban

Research output: Contribution to journal › Article › peer-review

Abstract

We show that causality constrains the sign of quartic Riemann corrections to the Einstein-Hilbert action. Our constraint constitutes a restriction on candidate theories of quantum gravity.
