Holographic symmetry algebra for the MHV sector revisited

Shamik Banerjee, Mousumi Maitra, Raju Mandal +1

We revisit the holographic symmetry algebra in the MHV sector. We find an infinite dimensional Abelian symmetry algebra whose generators are the conformally soft negative helicity…

Worldsheet CFT $_{2}$ and Celestial CFT $_{2}$ : An AdS $_{3}$ -CFT $_{2}$ perspective

Shamik Banerjee, Nishant Gupta, Sagnik Misra

Celestial CFT $_{d}$ is the putative dual of quantum gravity in asymptotically flat $(d + 2)$ dimensional space time. We argue that a class of Celestial CFT $_{d}$ can be engineered via Ad…
