Fontanella-Torrielli paper on AdS 3 superstrings accepted to Physical Review D

superstringThe paper “Massless sector of AdS 3 superstrings: a geometric interpretation” co-authored by Andrea Fontanella and Alessandro Torrielli, has been accepted for publication in Physical Review D.  The arXiV version is available here. In the paper, they study the recently discovered q-deformed Poincare’ supersymmetry of the AdS_3/CFT_2 integrable massless scattering, and demonstrate how the S-matrix is invariant under boosts. The paper provides a list of possible alternative interpretations of the emergent geometric picture, including a one-dimensional auxiliary Schroedinger problem. The claims are supported by performing a simplified algebraic Bethe ansatz, which bears some resemblance to antiferromagnets.
