Title: Massless scattering in lower-dimensional AdS/CFT

Abstract: In recent years the framework of AdS/CFT integrability has seen one particular paradigm change due to the appearance of massless modes in the associated scattering problem. We shall briefly recap, following Zamolodchikov, ideas on massless integrable scattering. We shall then translate this scenario to the case of AdS3/CFT2, and demonstrate the appearance of a 2D relativistic critical theory in the BMN limit of the integrable scattering problem. We will study the thermodynamic Bethe Ansatz (TBA) of this theory, and reflect on recent work such as the one by Abbott and Aniceto which might help formulating a TBA for the full theory. This talk is primarily based on work with R. Borsato, A. Fontanella, O. Ohlsson Sax, A. Sfondrini, B. Stefanski and J. Stroemwall.
