论文摘要
在本说明中，我们展示了1循环的精确校正如何由散射振幅的IR差异引起的均匀的软重力定理匹配到二次校正到从BMS Flux代数计算出的软电荷。在此过程中，我们研究了BMS通量结构如何将天体钻石框架扩展到非线性秩序和非平凡的真空，并为天体CFT提供天然对称发生器。
In this note we show how the 1-loop exact correction to the subleading soft graviton theorem arising from IR divergences of scattering amplitudes matches onto the quadratic corrections to the soft charges computed from the BMS flux algebra. In the process, we examine how the BMS flux construction extends the celestial diamond framework to non-linear order and non-trivial vacua, and provides the natural symmetry generators for Celestial CFT.
