Revisiting the shadow stress tensor in celestial CFT
Abstract We revisit the standard construction of the celestial stress tensor as a shadow of the subleading conformally soft graviton. In its original formulation there is an obstruction to reproducing the expected TT ¯ $$ \overline{TT} $$ OPE in the double soft limit. We propose a modification to th...
