论文摘要
最近，在标量调整理论的背景下制定了扰动的有效磁场理论（EFT）。在这里，我们概括了EFT动作中的系数与协方差理论之间的词典，以适应移位和反射对称性二次高阶高阶量表理论，包括DHOST以及U-DOLSTOR。然后，我们使用EFT动作来研究具有静态标量表的静态和球形对称的黑洞背景上的奇数扰动的动力学。最后，我们获得了可以使用的广义regge-wheeler方程，例如确定准模式和潮汐爱数字的光谱。
Recently, the Effective Field Theory (EFT) of perturbations on an arbitrary background metric with a timelike scalar profile was formulated in the context of scalar-tensor theories. Here, we generalize the dictionary between the coefficients in the EFT action and those in covariant theories to accommodate shift- and reflection-symmetric quadratic higher-order scalar-tensor theories, including DHOST as well as U-DHOST. We then use the EFT action to study the dynamics of odd-parity perturbations on a static and spherically symmetric black hole background with a timelike scalar profile. Finally, we obtain the generalized Regge-Wheeler equation that can be used, e.g., to determine the spectrum of quasinormal modes and tidal Love numbers.
