Infinite-dimensional R-matrices for the relativistic scattering of massless modes on AdS2

Abstract

Abstract We construct infinite-dimensional R-matrices that generalise the relativistic scattering of massless modes with the same chirality on AdS2 near the Berestein-Maldacena-Nastase vacuum. We show that the infrared limit of the R-matrices reproduces finite-dimensional scattering of massless modes on AdS2, from which the R-matrices borrow modified braiding unitary. We also prove that the R-matrices enjoy an infinite-dimensional symmetry superalgebra that embeds that of AdS2. Finally, we verify that the R-matrices are also invariant under crossing symmetry.
