Modified celestial amplitude in Einstein gravity
Shamik Banerjee, Sudip Ghosh, Pranjal Pandey +1
In this paper we evaluate the modified celestial amplitude for gravitons and gluons, as defined in arXiv:1801.10171[hep-th]. We find that the modified (tree) amplitude is finite fo…

Conformal properties of soft operators -- 2 : Use of null-states
Shamik Banerjee, Pranjal Pandey
Representations of the (Lorentz) conformal group with the soft operators as highest weight vectors have two universal properties, which we clearly state in this paper. Given a soft…

Conformal properties of soft-operators - 1 : Use of null-states
Shamik Banerjee, Pranjal Pandey, Partha Paul
Soft-operators, loosely speaking, are operators which create or annihilate zero energy massless particles on the celestial sphere in Minkowski space. The Lorentz group acts on the…
