Some Quantum Aspects of D=3 Space-Time Massive Gravity
arXiv:gr-qc/9611049
Abstract
We discuss some features of Einstein-Proca gravity in D=3 and 4 space-times. Our study includes a discussion on the tree-level unitarity and on the issue of light deflection in 3D gravity in the presence of a mass term.
