Comments on Topologically Massive Gravity with Propagating Torsion
arXiv:hep-th/9903127 · doi:10.1088/0264-9381/17/4/306
Abstract
We study and discuss some of the consequences of the inclusion of torsion in 3D Einstein-Chern-Simons gravity. Torsion may trigger the excitation of non-physical modes in the spectrum. Higher-derivative terms are then added up and tree-level unitarity is contemplated.
