On the degrees of freedom of R 2 gravity in flat spacetime

Abstract We study the degrees of freedom of R 2 gravity in flat spacetime with two approaches. By rewriting the theory a la Stueckelberg, and implementing Lorentz-like gauges to the metric perturbations, we confirm that the pure theory propagates one scalar degree of freedom, while the full theory c...
