摘要

本文利用自旋世界线量子场论的技术，计算了动力学chen - simons理论中黑洞散射事件的WQFT配分函数，特别是对角相位。我们考虑了旋转黑洞的散射，并强调了计算配分函数的必要细节。我们使用分项积分（IBP）简化和微分方程技术给出了基本双环积分的ϵ-expansion，然后我们利用它来计算高达3PM的线性有序自旋对角相位。此外，我们还讨论了相位与黑洞自旋方向的关系。

Bootstrapping the spinning two body problem in dynamical Chern-Simons gravity using worldline QFT

In this paper, we compute the WQFT partition function, specifically the eikonal phase in a black hole scattering event in the dynamical Chern-Simons theory, using the techniques of spinning worldline quantum field theory. We consider the scattering of spinning black holes and highlight the necessary details for the calculation of the partition function. We present the ϵ-expansion of the essential two-loop integrals using Integration-by-Parts (IBP) reduction and differential equation techniques, which we then utilize to compute the linear-in-order spin eikonal phase up to 3PM. Additionally, we discuss the dependence of the phase on the spin orientations of the black holes.
