标题： Post-Minkowskian Theory Meets the Spinning Effective-One-Body Approach for Bound-Orbit Waveforms

摘要： 由散射振幅和基于世界线的方法的进步所推动，近年来我们在计算引力二体散射可观测量方面取得了显著进展。 这些可观测量有效地概括了弱场和高速度情形（后闵可夫斯基，PM）下的引力二体问题，适用于束缚二体问题和引力波建模。 我们利用PM数据，在有效单体（EOB）形式下构建了一个非进动旋转黑洞的完整 inspiral-merger-ringdown 波形模型：SEOBNR-PM。 该模型紧密基于广泛成功的SEOBNRv5模型，该模型被LIGO-Virgo-KAGRA合作组织使用，其关键新特性是通过在微扰PM展开中匹配二体散射角来推导出的EOB哈密顿量。 该模型表现非常出色，与441个数值相对论（NR）模拟相比，其中位不匹配 somewhat 低于同样校准的SEOBNRv5版本。 与NR的结合能比较也显示出比SEOBNRv5更好的一致性，尽管后者包含额外的NR模拟校准。 显示英文摘要

摘要： Driven by advances in scattering amplitudes and worldline-based methods, recent years have seen significant progress in our ability to calculate gravitational two-body scattering observables. These observables effectively encapsulate the gravitational two-body problem in the weak-field and high-velocity regime (post-Minkowskian, PM), with applications to the bound two-body problem and gravitational-wave modeling. We leverage PM data to construct a complete inspiral-merger-ringdown waveform model for non-precessing spinning black holes within the effective-one-body (EOB) formalism: SEOBNR-PM. This model is closely based on the highly successful SEOBNRv5 model, used by the LIGO-Virgo-KAGRA Collaboration, with its key new feature being an EOB Hamiltonian derived by matching the two-body scattering angle in a perturbative PM expansion. The model performs remarkably well, showing a median mismatch against 441 numerical-relativity (NR) simulations that is somewhat lower than a similarly calibrated version of SEOBNRv5. Comparisons of the binding energy with NR also demonstrate better agreement than SEOBNRv5, despite the latter containing additional calibration to NR simulations.
