最近，有效场理论（EFT）的扰动的任意背景度量与类时标量轮廓制定的标量张量理论的背景下。在这里，我们推广的字典之间的系数EFT行动和协变理论，以适应移位和反射对称的二次高阶标量张量理论，包括DHOST以及U-DHOST。然后，我们使用EFT行动的研究动态的奇宇称扰动的静态和球对称黑洞背景的类时标量配置文件。最后，我们得到了广义Regge-Wheeler方程，它可以用来确定准正规模的谱和潮汐Love数。
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, eg, to determine the spectrum of quasinormal modes and tidal Love numbers.
