论文摘要

广义的重力理论代表了一类有趣的矢量调节理论,其中只有三个传播的自由度。在这项工作中,我们提出了一个对Proca理论的新电静电性重力类似物,在该重力理论中,由于基于扭转的重力的低阶性质,广义的Proca框架被扩展。我们开发了新的行动贡献,并探讨了该制度中弗里德曼方程的示例。我们发现,远程处理理论提供了更大类模型的可能性,在这些模型中确实会影响背景宇宙学。

Generalised Proca theories of gravity represent an interesting class of vector-tensor theories where only three propagating degrees of freedom are present. In this work, we propose a new teleparallel gravity analog to Proca theories where the generalised Proca framework is extended due to the lower order nature of torsion based gravity. We develop a new action contribution and explore the example of the Friedmann equations in this regime. We find that teleparallel Proca theories offer the possibility of a much larger class of models in which do have an impact on background cosmology.
