| 英文摘要 | In a previous article [1], we have argued that low's sub-leading soft photon theorem can be recovered as a ward identity associated to the same large gauge transformations that control the leading piece of the theorem. the key for that was to link the energy expansion displayed in the soft theorem to a 1/r expansion that we can perform in the associated asymptotic charge. we expect this idea to be valid in general, and here we provide compelling evidence for it by showing how the same method works in the case of einstein-hilbert gravity. more precisely, we are able to derive the three orders of the tree-level soft graviton theorem simply from the bms supertranslation charge, known to give rise to the leading soft graviton theorem. in particular, we do not need to invoke superrotations (nor extended superrotations) at any point of the argument. |
