论文摘要
我们在最简单的标量张量理论上得出了因果关系的约束，在该理论中，黑洞与一般相对性预测的不同，标量耦合到高斯 - 骨网或Chern-Simons项。要求在这些有效田地理论的有效性方面，我们发现时间的进步是无法观察到的，我们发现它们的截止必须与黑洞的schwarzschild radius相同的参数尺寸，非标准效应是阶效应。对于当前重力波检测器范围内的天体物理黑洞，这意味着在km处的截止长度。我们进一步探索了可能与紫外线完成规模相关的领先的其他高维操作员，并讨论了它们对重力波科学的现象学意义。
We derive causality constraints on the simplest scalar-tensor theories in which black holes differ from what General Relativity predicts, a scalar coupled to the Gauss-Bonnet or the Chern-Simons terms. Demanding that time advances are unobservable within the regime of validity of these effective field theories, we find their cutoff must be parametrically of the same size as the inverse Schwarzschild radius of the black holes for which the non-standard effects are of order one. For astrophysical black holes within the range of current gravitational wave detectors, this means a cutoff length at the km. We further explore the leading additional higher-dimensional operators potentially associated with the scale of UV completion and discuss their phenomenological implications for gravitational wave science.
