Subsubleading soft graviton symmetry and MHV graviton scattering amplitudes
Abstract In [8] it was shown that supertranslation and SL 2 ℂ ¯ $$ \overline{\mathrm{SL}\left(2,\mathbb{C}\right)} $$ 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...
