An 'exceptional' form for symmetries in maximal supergravity
Sudarshan Ananth, Nipun Bhave
The global symmetries in maximally supersymmetric theories of gravity in are shown to have a universal form in light-cone superspace. The procedure for deriving an all orde…
Exceptional symmetries in light-cone superspace
Sudarshan Ananth, Nipun Bhave
We construct maximal supergravity in five-dimensions by 'oxidizing' the four-dimensional theory. The relevant symmetries, the unitary symplectic group and…
Deriving interaction vertices in higher derivative theories
Sudarshan Ananth, Nipun Bhave, Chetan Pandey +1
We derive cubic interaction vertices for a class of higher-derivative theories involving three arbitrary integer spin fields. This derivation uses the requirement of closure of the…
BMS symmetry in gravity: Front form versus Instant form
Sudarshan Ananth, Sucheta Majumdar
In General Relativity, the allowed set of diffeomorphisms or gauge transformations at asymptotic infinity forms the BMS group, an infinite-dimensional extension of the Poincaré gro…
Soft factors and interaction vertices from light-cone actions
Sudarshan Ananth, Chetan Pandey, Saurabh Pant
Universal factors associated with the emission of a soft boson in gauge theories and gravity, formulated in the light-cone gauge, are presented. The inverse-soft method, for constr…
The structure of interaction vertices in pure gravity in the light-cone gauge
Sudarshan Ananth, Nipun Bhave, S. I. Aadharsh Raj
The first truly non-MHV interaction vertices in the light-cone formulation of pure gravity appear at order 6. From a closed form expression, for gravitation in the light-cone gauge…
