Asymptotic Symmetry algebra of Supergravity
Nabamita Banerjee, Tabasum Rahnuma, Ranveer Kumar Singh
The asymptotic symmetry algebra of supergravity was recently constructed using the well-known D celestial CFT (CCFT) technique in ArXiv: 2007.03785. In this pape…
Soft and Collinear Limits in Supergravity using Double Copy Formalism
Nabamita Banerjee, Tabasum Rahnuma, Ranveer Kumar Singh
It is known that supergravity is dual to super Yang-Mills (SYM) via the double copy relation. Using the explicit relation between scattering amplitu…
Asymptotic Symmetry of Four Dimensional Einstein-Yang-Mills and Einstein-Maxwell Theory
Nabamita Banerjee, Tabasum Rahnuma, Ranveer Kumar Singh
Asymptotic symmetry plays an important role in determining physical observables of a theory. Recently, in the context of four dimensional asymptotically flat pure gravity and $\mat…
Bhargava's Cube and Black Hole Charges
Nabamita Banerjee, Ajit Bhand, Suvankar Dutta +2
Black holes in a class of string compactifications, known as STU models, carry four electric and four magnetic charges. Furthermore a duality group, given by the product of three c…
