MHV Gluon Scattering Amplitudes from Celestial Current Algebras
Shamik Banerjee, Sudip Ghosh
We show that the Mellin transform of an -point tree level MHV gluon scattering amplitude, also known as the celestial amplitude in pure Yang-Mills theory, satisfies a system of…

MHV Graviton Scattering Amplitudes and Current Algebra on the Celestial Sphere
Shamik Banerjee, Sudip Ghosh, Partha Paul
The Cachazo-Strominger subleading soft graviton theorem for a positive helicity soft graviton is equivalent to the Ward identities for currents. This n…

BMS Symmetry of Celestial OPE
Shamik Banerjee, Sudip Ghosh, Riccardo Gonzo
In this paper we study the BMS symmetry of the celestial OPE of two positive helicity gravitons in Einstein theory in four dimensions. The celestial OPE is obtained by Mellin trans…
