Boundary scattering in massless AdS 3

Abstract

Abstract We study the boundary integrability problem of the massless sector of AdS 3 × S 3 × T 4 string theory. Exploiting the difference-form of the massless scattering theory, we find a very simple and exhaustive list of reflection matrices for all the possible boundary coideal subalgebras — singlet and vector representations, right and left boundary — and check basic properties of our solutions, primarily the boundary Yang-Baxter equation, for all possible combinations of scattering particles.
