论文摘要
我们研究了在低能量有效的重力理论中，重力波在黑洞背景上的传播，其中较高的曲率算子捕获了重场的效果。根据集成的颗粒的自旋，与其他物种观察到的因果结构相比，低能量处的重力波的速度可以是超亮型或肾小球。然而，有趣的是，重力波总是在黑洞地平线上完全是腔内的，这意味着地平线是所有物种都相同定义的。我们进一步计算了由较高维曲率算子引起的准频率的校正，并突出了低能有效场引起的校正。
We investigate the propagation of gravitational waves on a black hole background within the low energy effective field theory of gravity, where effects from heavy fields are captured by higher dimensional curvature operators. Depending on the spin of the particles integrated out, the speed of gravitational waves at low energy can be either superluminal or subluminal as compared to the causal structure observed by other species. Interestingly however, gravitational waves are always exactly luminal at the black hole horizon, implying that the horizon is identically defined for all species. We further compute the corrections on quasinormal frequencies caused by the higher dimensional curvature operators and highlight the corrections arising from the low energy effective field.
