论文摘要
我们计算了涉及引力辐射自由度的交换的特定相互作用的两体散射角的贡献，包括非线性记忆过程和辐射反应效应的平方。我们的计算直接从运动方程进行，从而计算保守和耗散过程的整体效果。此类贡献原则上提供了最后缺少的成分，以在第四次牛顿后第四次以第四次后订单计算散射角度。
We compute the contribution to the two-body scattering angle of a specific class of interactions involving the exchange of gravitational radiative degrees of freedom, including the nonlinear memory process and square of radiation reaction effects. Our computation is performed directly from the equations of motion, thus computing the overall effect of both conservative and dissipative processes. Such contributions provide in principle the last missing ingredients to compute the scattering angle at fifth post-Newtonian, at fourth post-Minkowskian order.
