High Energy Theory | Sabrina Gonzalez Pasterski - Princeton | "4D Scattering as 2D Correlators"

Fri, Oct 18, 2019, 1:45 pm

The asymptotic symmetry algebra of asymptotically flat spacetimes implies an infinity of conserved charges for 4D scattering which can be neatly recast as 2D conformal Ward identities. We cover recent progress on the proposed 4D/2D dictionary starting from the conformally soft modes that appear as currents and extending our map to a basis for finite energy scattering states.
