论文摘要
在这项工作中，我们研究了$ d $ d $二维的时空的高源性重力，由于嵌入了$ 4D $ Minkowski SpaceTime中的2个教室，因此出现了质量术语。我们考虑了DGP Braneworld模型的共振质量项对更高衍生的大型重力的影响。此外，我们将重力Chern-Simons和Ricci-Cotton术语添加到该模型中，并使用Barnes-Rivers旋转投影仪的基础评估Graviton传播器。使用获得的繁殖器，我们继续讨论模型的一致性，编写分散关系以及分析因果关系和单位性。
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.
