Some Quantum Aspects of Three-Dimensional Einstein-Chern-Simons-Proca Massive Gravity

Abstract

We present a 3-dimensional model for massive gravity with masses induced by topological (Chern-Simons) and Proca-like mass terms. Causality and unitarity are discussed at tree-level. Power-counting renormalizability is also contemplated.
