dc.description.abstractWe present the most general covariant ghost-free gravitational action in a Minkowski vacuum. Apart from the much studied f(R) models, this includes a large class of nonlocal actions with improved UV behavior, which nevertheless recover Einstein’s general relativity in the IR. © 2012 American Physical Societyen_US
