The paper “The S-matrix algebra of the AdS_2 X S_2 superstring“, co-authored by Ben Hoare (ETH, Zürich), Antonio Pittelli, and Alessandro Torrielli, has been accepted for publication as a regular article in Physical Review D. In the paper they find the Yangian algebra responsible for the integrability of the AdS2 X S2 X T6 superstring in the planar limit.  The final form preprint can be found on the arXiv here.
