论文摘要
从5点振幅的领先柔软项开始，涉及重力和两个Kerr黑洞，将其分解为弹性振幅的产物，而无需重力和领先的软因子，我们计算了对两循环Eikonal假想部分的红外差异贡献。然后，使用分析性和交叉对称性，我们确定了对两环碘的实际部分的辐射贡献，并从中确定与轨道角动量相一致的旋转偏转角的辐射部分，角度动量的损失和能量频率零的零频谱的零频谱和任何旋转的旋转和任何旋转的旋转方向。对于Spin One，我们发现与超对称世界形式主义获得的最新结果完全同意。
Starting from the leading soft term of the 5-point amplitude, involving a graviton and two Kerr black holes, that factorises into the product of the elastic amplitude without the graviton and the leading soft factor, we compute the infrared divergent contribution to the imaginary part of the two-loop eikonal. Then, using analyticity and crossing symmetry, we determine the radiative contribution to the real part of the two-loop eikonal and from it the radiative part of the deflection angle for spins aligned to the orbital angular momentum, the loss of angular momentum and the zero frequency limit of the energy spectrum for any spin and for any spin orientation. For spin one we find perfect agreement with recent results obtained with the supersymmetric worldline formalism.
