标题： Graviton partial waves and causality in higher dimensions

摘要： 引力相互作用是否遵循相对论和量子力学的基本原理？ 我们证明，满足这些假设的任何引力子 S-矩阵在低能下都不能与广义相对论有显著差异。 我们在时空维度 D >= 5 中，以新高自旋态的质量 M 为单位，给出了潜在修正幅度的严格界限，在此维度中 S-矩阵不会受到红外模糊性的影响。 关键的新元素是此过程的完整 SO(D-1) 部分波集，我们展示了如何通过 Young 图表操作有效地计算它们。 我们记录了关于全息共形理论中心电荷的新界限。 显示英文摘要

摘要： Do gravitational interactions respect the basic principles of relativity and quantum mechanics? We show that any graviton S-matrix that satisfies these assumptions cannot significantly differ from General Relativity at low energies. We provide sharp bounds on the size of potential corrections in terms of the mass M of new higher-spin states, in spacetime dimensions D>=5 where the S-matrix does not suffer from infrared ambiguities. The key novel ingredient is the full set of SO(D-1) partial waves for this process, which we show how to efficiently compute with Young tableau manipulations. We record new bounds on the central charges of holographic conformal theories.
