Note on higher spins and holographic symmetry algebra
Shamik Banerjee, Suman Guchait, Raju Mandal +1
In this paper we discuss a higher spin extension of the holographic symmetry algebra for graviton and gluon. Our primary observation is that in the presence of higher spin particle…
All loop soft photon theorems and higher spin currents on the celestial sphere
Shamik Banerjee, Raju Mandal, Biswajit Sahoo
Soft factorization theorems can be reinterpreted as Ward identities for (asymptotic) symmetries of scattering amplitudes in asymptotically flat space-time. In this paper we study t…
Boundary operators in asymptotically flat space-time
Shamik Banerjee
In \cite{Jain:2023fxc} the authors have proposed an interesting framework for studying holography in flat space-time. In this note we explore the relationship between their proposa…
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 and Celestial CFT : An AdS-CFT perspective
Shamik Banerjee, Nishant Gupta, Sagnik Misra
Celestial CFT is the putative dual of quantum gravity in asymptotically flat dimensional space time. We argue that a class of Celestial CFT can be engineered via Ad…
