Subsubleading soft graviton symmetry and MHV graviton scattering amplitudes (2104.02546v5)
Published 6 Apr 2021 in hep-th
Abstract: In arXiv:2008.04330 it was shown that supertranslation and $\overline{SL(2,\mathbb C)}$ current algebra symmetries, corresponding to leading and subleading soft graviton theorems, are enough to determine the tree level MHV graviton scattering amplitudes. In this note we clarify the role of subsubleading soft graviton theorem in this context.
