论文摘要
我们通过分析其对旋转天文学二元系统的观察的影响，通过较高的重力拉格朗日语言中较高的曲率项来研究对一般相对性进行短距离修改的可能性。通过使用应用于2体问题的有效现场理论方法，可以设置伴随高曲率项的短距离量表上的通用下限。特别是，我们通过在二元系统中得出旋转能量，辐射发射过程和旋转进动方程中的自旋依赖性效应来扩展已知结果，这是观察到紧凑型二进制凝聚力的重力波检测中自旋依赖性效应的基本成分，而双二进制脉冲脉冲中的旋转液则是旋转的。
We investigate the possibility of testing short distance modifications to General Relativity via higher curvature terms in the fundamental gravity Lagrangian by analysing their impact on observations of spinning astronomical binary systems. By using effective field theory methods applied to the 2-body problem, generic lower bounds on the short-distance scale accompanying high curvature terms can be set. In particular we extend known results by deriving spin-dependent effects in binding energy, radiation emission process, and spin precession equations in binary systems, which are the fundamental ingredients to observe spin-dependent effects in gravitational wave detections from compact binary coalescences and spin precession in double binary pulsars.
