论文摘要
在本论文中，我们介绍了直接从散射幅度中直接从仪表理论和重力中的经典可观察物计算的研究。特别是，我们讨论了现代振幅技术在一个，散射和有界场景的两体问题中的直接应用，以及在经典的电动力学和重力中，尤其强调一般的旋转效应，并在四个时空尺寸中。在这些可观察到的东西中，我们在两体问题中具有保守的线性冲动和辐射波形，以及用于从经典旋转紧凑物体散射波的差分横截面。还讨论了经典软定理在经典辐射计算中的含义。此外，考虑了双复制物的正式方面，以进行大规模旋转物质及其在经典的两体环境中的应用。最后，提出了最小的耦合引力康普顿振幅与重力波的散射之间的关系。
In this thesis we present a study of the computation of classical observables in gauge theories and gravity directly from scattering amplitudes. In particular, we discuss the direct application of modern amplitude techniques in the one, and two-body problems for both, scattering and bounded scenarios, and in both, classical electrodynamics and gravity, with particular emphasis on spin effects in general, and in four spacetime dimensions. Among these observables we have the conservative linear impulse and the radiated waveform in the two-body problem, and the differential cross section for the scattering of waves off classical spinning compact objects. Implications of classical soft theorems in the computation of classical radiation are also discussed. Furthermore, formal aspects of the double copy for massive spinning matter, and its application in a classical two-body context are considered. Finally, the relation between the minimal coupling gravitational Compton amplitude and the scattering of gravitational waves off the Kerr black hole is presented.
