Extending the Spin Projection Operators for Gravity Models with Parity-Breaking in 3-D
arXiv:1001.2784 · doi:10.1016/j.physleta.2010.06.048
Abstract
We propose a new basis of spin-operators, specific for the case of planar theories, which allows a Lagrangian decomposition into spin-parity components. The procedure enables us to discuss unitarity and spectral properties of gravity models with parity-breaking in a systematic way.
