# Current Algebra on the Conformal Boundary and the Variables of Quantum Gravity

@article{Banks2015CurrentAO, title={Current Algebra on the Conformal Boundary and the Variables of Quantum Gravity}, author={Thomas Banks}, journal={arXiv: High Energy Physics - Theory}, year={2015} }

I argue that scattering theory for massless particles in Minkowski space should be reformulated as a mapping between past and future representations of an algebra of densities on the conformal boundary. These densities are best thought of as living on the momentum space light cone dual to null infinity, which describes the simultaneous eigenstates of the BMS generators. The currents describe the flow of other quantum numbers through the holographic screen at infinity. They are operator valued…

It is shown that there exists an infinite tower of fermionic symmetries in pure d=4, N=1 supergravity on an asymptotically flat background, and that these charges commute into charges associated with the (unextended) Bondi-Metzner-Sachs group, providing a supersymmetrization of the BMS translations.
