Energy definition for quadratic curvature gravities [PDF]
Ahmet BaykalA 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.View original: http://arxiv.org/abs/1212.0432
