论文摘要
我们得出了一个有效的方程式和动作，用于引力波（GW）的传播，并在时间，频率和极化依赖于有效速度的时间内编码相互作用和自我相互作用的影响。就适当定义的有效指标而言，有效的动作将表格采取无质量的klein-gordon行动。 这种有效的方法预测，对于与爱因斯坦框架耦合的理论，重力和电磁（EM）光度距离之间的比率取决于有效速度，而对于Jordan框架，耦合的耦合取决于有效的Planck质量。我们讨论GW-EM距离比的频率和极化依赖性如何为一般相对性及其修改提供了新的测试，而更多的是GWS与其他领域的相互作用。
We derive an effective equation and action for the propagation of gravitational waves (GW), encoding the effects of interaction and self-interaction in a time, frequency and polarization dependent effective speed. In terms of an appropriately defined effective metric, the effective action takes the form a massless Klein-Gordon action. This effective approach predicts that for theories with matter coupled to the Einstein frame metric the ratio between gravitational and electromagnetic (EM) luminosity distance depends on the effective speed, while for Jordan frame matter coupling it depends on the effective Planck mass. We discuss how the frequency and polarization dependence of the GW-EM distance ratio provides a new test of general relativity and its modifications, and more in general of the interaction of GWs with other fields.
