Energy definition for quadratic curvature gravities
arXiv:1212.0432 · doi:10.1103/PhysRevD.86.127501
Abstract
A conserved current for generic quadratic curvature gravitational models is defined, and it is shown that, at the linearized level, it corresponds to the Deser-Tekin charges. An explicit expression for the charge for new massive gravity in three dimensions is given. Some implications of the linearized equations are discussed.
