摘要

A model of gravity is presented involving a symmetric two-tensor in Minkowski space-time based on spontaneous Lorentz symmetry breaking triggered by a potential. The gravitons in this model arise as the Nambu-Goldstone (NG) bosons of the spontaneously broken symmetries. The Lagrangian is obtained by the application of a bootstrap procedure based on the principle of consistent coupling to the total energy energy-momentum tensor. At low energy, the resulting lagrangian for the NG modes is equivalent to General Relativity in a fixed gauge, the metric arising a a combination of the two-tensor and the Minkowski metric. We discuss some issues related to quantization.
