From massive gravity to modified general relativity II
arXiv:0912.1112 · doi:10.1007/s10714-010-1115-0
Abstract
We continue our investigation of massive gravity in the massless limit of vanishing graviton mass. From gauge invariance we derive the most general coupling between scalar matter and gravity. We get further couplings beside the standard coupling to the energy-momentum tensor. On the classical level this leads to a further modification of general relativity.
