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…

Singularity Structure of the Four Point Celestial Leaf Amplitudes

Raju Mandal, Sagnik Misra, Partha Paul +1

In this paper, we study the four-point celestial leaf amplitudes of massless scalar and MHV gluon scattering. These leaf amplitudes are non-distributional decompositions of the cel…

All $S$ invariant gluon OPEs on the celestial sphere

Shamik Banerjee, Raju Mandal, Sagnik Misra +2

$S$ algebra is an infinite dimensional Lie algebra which is known to be the symmetry algebra of some gauge theories. It is a "coloured version" of the $w_{1 + \infty}$ . In this paper…
