论文摘要
在本文中，我们首次得出了在牛顿后（PN）膨胀的近代领导顺序上的通用紧凑型二进制文件的完整重力四分之一的旋转相互作用。该推导基于引诱旋转对象的有效场理论及其最近的扩展，其中应考虑新型的全球耦合，以及在曲率下旋转粒子对二次序列的有效作用的扩展。后一个扩展需要在该领域出现的新威尔逊系数。这项工作将Precision Frontier用旋转在第五pn（5pn）的顺序上以最大旋转的紧凑型物体的形式推动，同时又向我们告知我们带有更高旋转的重力康普顿散射。
In this paper we derive for the first time the complete gravitational quartic-in-spin interaction of generic compact binaries at the next-to-leading order in the post-Newtonian (PN) expansion. The derivation builds on the effective field theory for gravitating spinning objects, and its recent extensions, in which new type of worldline couplings should be considered, as well as on the extension of the effective action of a spinning particle to quadratic order in the curvature. The latter extension entails a new Wilson coefficient that appears in this sector. This work pushes the precision frontier with spins at the fifth PN (5PN) order for maximally-spinning compact objects, and at the same time informs us of the gravitational Compton scattering with higher spins.
