论文摘要
我们提出了一个新的四弹体的新计算，该计算在两个任意旋转体的散射过程中被辐射到引力波中。我们的结果准确地以$ g $领先订单，在旋转中进行二次订单，以及速度中的所有订单，是通过使用基于Routhian的Worldline有效的现场理论形式主义来得出的，并与一系列分析技术一起评估LOOP积分。尽管非二进制文件仅沿其相对速度的方向辐射动量，但我们表明，旋转的包含允许在所有三个空间方向上均可损失动量损失。我们还验证了我们对辐射能量的表达与纽顿后理论中最先进的计算中的重叠术语一致。
We present a novel calculation of the four-momentum that is radiated into gravitational waves during the scattering of two arbitrarily spinning bodies. Our result, which is accurate to leading order in $G$, to quadratic order in the spins, and to all orders in the velocity, is derived by using a Routhian-based worldline effective field theory formalism in concert with a battery of analytic techniques for evaluating loop integrals. While nonspinning binaries radiate momentum only along the direction of their relative velocity, we show that the inclusion of spins generically allows for momentum loss in all three spatial directions. We also verify that our expression for the radiated energy agrees with the overlapping terms from state-of-the-art calculations in post-Newtonian theory.
