Coupling of Gravity to Matter via SO(3,2) Gauge Fields
arXiv:gr-qc/0409058 · doi:10.1007/BF02105318
Abstract
We consider gravity from the quantum field theory point of view and introduce a natural way of coupling gravity to matter by following the gauge principle for particle interactions. The energy-momentum tensor for the matter fields is shown to be conserved and follows as a consequence of the dynamics in a spontaneously broken SO(3,2) gauge theory of gravity. All known interactions are described by the gauge principle at the microscopic level.
