弯曲时空背景中引力子的传播

On graviton propagation in curved space-time background

E. V. Arbuzova, A. D. Dolgov, L. A. Panasenko

摘要:

分析了描述引力波(GW)在任意弯曲时空背景中传播的方程。发现了传统的均匀各向同性Friedmann宇宙学中所没有的新项,并给出了这些新项在现实度规中出现的例子。对甚低频GW的可能影响进行了简要讨论。

英文摘要:

Equation describing propagation of gravitational waves (GW) over arbitrary curved space-time background is analyzed. New terms, which are absent in the conventional homogeneous and isotropic Friedmann cosmology, are found. Some examples of realistic metric, where these new terms manifest themselves, are presented. Possible implications to very low frequency GW are briefly discussed.
