In this study, the higher-derivative massive gravity in D-dimensional space-time is investigated. The mass term is introduced by a 2-brane embedded in a 4D Minkowski spacetime. The effect of a resonance mass term from the DGP braneworld model is considered. Additionally, the gravitational Chern-Simons and Ricci-Cotton terms are added to the model and the graviton propagator is evaluated using a basis of Barnes-Rivers spin projectors. The consistency of the model, dispersion relations, and causality and unitarity are discussed based on the obtained propagator.
In this work, we study the higher-derivative massive gravity in D-dimensional space-time with the mass term arisen due to a 2-brane embedded in a 4D Minkowski spacetime. We consider the effect of a resonance mass term from the DGP braneworld model for the higher-derivative massive gravity. Moreover, we add the gravitational Chern-Simons and Ricci-Cotton terms to this model and evaluate the graviton propagator using a basis of Barnes-Rivers spin projectors. Using the obtained propagator, we proceed with discussing the consistency of the model, writing the dispersion relations, and analyzing causality and unitarity.
