A canonical realization of the Weyl BMS symmetry

High Energy Physics - Theory 2020-11-11 v2

Abstract

We construct a free field realization of an extension of the BMS algebra in 2+12+1 dimensional space-time. Besides the supertranslations and superrotations, the extension contains an infinite set of superdilatations. We also comment the difficulties that appear when trying to extend the algebra to that of the full conformal group.
