Towards celestial CFT dual of 4d conformal gravity
Nirmal Ghorai, Partha Paul, Nemani V. Suryanarayana
We compute tree-level celestial operator product expansions (OPE) in a bosonic sub-sector of the Berkovits-Witten conformal supergravity from the scattering amplitudes in the MHV c…
Celestial dual of conformal gravity MHV amplitudes: an OPE analysis
Nirmal Ghorai, Partha Paul, Nemani V. Suryanarayana
In an earlier paper [arXiv:2511.03669] we extracted the OPE of celestial CFT operator duals of positive helicity graviton and scalar particles from the Mellin transformed relevant…
Super-Giants in Gutowski-Reall Black Hole
Nayan Mondal, Nemani V. Suryanarayana
We present all bosonic giant and dual-giant type configurations of a probe D3-brane in the BPS single-parameter Gutowski-Reall black hole in 10d type IIB supergravity that do not b…
Chiral - symmetry of 3d conformal gravity
Nishant Gupta, Nemani V. Suryanarayana
We propose mixed boundary conditions for 3d conformal gravity consistent with variational principle in its second-order formalism that admit the chiral - alge…
