All invariant gluon OPEs on the celestial sphere
Shamik Banerjee, Raju Mandal, Sagnik Misra +2
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 . In this paper…
Celestial OPE in Self Dual Gravity
Shamik Banerjee, Harshal Kulkarni, Partha Paul
In this paper we compute the celestial operator product expansion between two outgoing positive helicity gravitons in the self dual gravity. It has been shown that the self dual gr…
An infinite family of invariant theories on the celestial sphere
Shamik Banerjee, Harshal Kulkarni, Partha Paul
In this note we determine the graviton-graviton OPE and the null states in any symmetric theory on the celestial sphere. Our analysis shows that there exists a discr…
MHV Gluon Scattering in the Massive Scalar Background and Celestial OPE
Shamik Banerjee, Raju Mandal, Akavoor Manu +1
In this paper we study the OPE between two positive helicity outgoing gluons in the celestial CFT for the Yang-Mills theory chirally coupled to a massive scalar background. This th…
