我们推广了[4-9]中发展的Worldline EFT公式，在长波近似下计算了旋转黑洞的非保守潮汐效应，这种长波近似对自旋量级的所有数量级都有效。我们给出了背景场中质量和角动量变化率的结果，并与以前用不同方法得到的计算结果一致。我们还给出了非保守运动方程和功率损耗/增益的新结果，它们分别从5pN和2.5pN级开始，表现为彭罗斯过程。
We generalize the worldline EFT formalism developed in [4–9] to calculate the non-conservative tidal effects on spinning black holes in a long wavelength approximation that is valid to all orders in the magnitude of the spin. We present results for the rate of change of mass and angular momentum in a background field and find agreement with previous calculations obtained by different techniques. We also present new results for both the non-conservative equations of motion and power loss/gain for a binary inspiral, which start at 5PN and 2.5PN order respectively and manifest the Penrose process.
