引力波产生和传播对广义相对论的参数化检验

Parameterized tests of general relativity with gravitational wave generation and propagation

Ke Wang

摘要:

对引力的任何修改不仅会影响引力波的产生,而且会影响引力波的传播。因此,只有GW产生或GW传播的广义相对论(GR)的测试将导致对偏差的高估。在这里,我们尝试使用一组参数来参数化GW生成和GW传播的修改,然后使用GW 150914测试GR。在最简单的情况下,我们发现引力子质量$μ<6.3\times10^{-23}{\rm eV/c^2}$在$90\%$ C. L.并且在$90\%$ C.L.处不存在与GR的偏差。

英文摘要:

Any modification on gravity would affect not only gravitational wave (GW) generation but also GW propagation. Therefore, tests of general relativity (GR) with only GW generation or GW propagation will lead to an overestimate for deviations. Here we try to use one set of parameters to parameterize the modifications on both GW generation and GW propagation and then test GR with GW150914. In our simplest case, we find that graviton mass $μ<6.3\times10^{-23}{\rm eV/c^2}$ at $90\%$ C.L. and there are no deviations from GR at $90\%$ C.L..
