A Secret Symmetry of the AdS/CFT S-matrix

Takuya Matsumoto, Sanefumi Moriyama, Alessandro Torrielli

Research output: Contribution to journalArticlepeer-review


We find a new quantum Yangian symmetry of the AdS/CFT S-matrix, which complements the original su(2|2) symmetry to gl(2|2) and does not have a Lie algebra analog. Our finding is motivated by the Yangian double structure discovered at the classical level.
