On the massless modes of the AdS3/CFT2 integrable systems

Ohlsson Sax, O., Torrielli, A. & Stefanski, B. (2013). On the massless modes of the AdS3/CFT2 integrable systems. Journal of High Energy Physics, 13(03), 109. doi: 10.1007/JHEP03(2013)109


We make a proposal for incorporating massless modes into the spin-chain of the AdS3/CFT2 integrable system. We do this by considering the α → 0 limit of the alternating d(2,1;α)2 spinchain constructed in arXiv:1106.2558. In the process we encounter integrable spin-chains with nonirreducible representations at some of their sites. We investigate their properties and construct their R-matrices in terms of Yangians.
