论文摘要
我们认为在有效的重力理论中,在两循环水平上可以重新分配的静态和球形对称脏黑洞的重力准模式。证明,使用\ cite {jaop}提出的WKB-Padé求和可以实现足够的精度来计算由Goroff-Sagnotti曲率术语引起的准模式的复杂频率的校正。结果表明,Goroff-Sagnotti校正(我们选择了耦合常数的符号)会增加基本模式的阻尼(最低基本模式除外)并降低了频率。我们认为,本文所采用的方法可用于分析高阶曲率项对准模式的影响以及许多需要高准确性的相关问题。
We consider gravitational quasinormal modes of the static and spherically-symmetric dirty black holes in the effective theory of gravity which is renormalizable at the two-loop level. It is demonstrated that using the WKB-Padé summation proposed in \cite{jaOp} one can achieve sufficient accuracy to calculate corrections to the complex frequencies of the quasinormal modes caused by the Goroff-Sagnotti curvature terms. It is shown that the Goroff-Sagnotti correction (with our choice of the sign of the coupling constant) increases damping of the fundamental modes (except for the lowest fundamental mode) and decreases their frequencies. We argue that the methods adopted in this paper can be used in the analysis of the influence of the higher-order curvature terms upon the quasinormal modes and in a number of related problems that require high accuracy.
