Yangian-symmetryThe paper “Secret symmetries of type IIB superstring theory on AdS3 x S3 x M4” by Antonio Pittelli, Alessandro Torrielli, & Martin Wolf has been accepted for publication in the Journal of Physics A: Mathematical and Theoretical. The paper establish features of so-called Yangian secret symmetries for AdS3 type IIB superstring backgrounds thus verifying the persistence of such symmetries to this new instance of the AdS/CFT correspondence. Specifically, they find two a priori different classes of secret symmetry generators. One class of generators, anticipated from the previous literature, is more naturally embedded in the algebra governing the integrable scattering problem. The other class of generators is more elusive, and somewhat closer in its form to its higher-dimensional AdS5 counterpart. All of these symmetries respect left-right crossing. In addition, by considering the interplay between left and right representations, they gain a new perspective on the AdS5 case. They also study the RTT-realisation of the Yangian in AdS3 backgrounds thus establishing a new incarnation of the Beisert-de Leeuw construction. The final-form preprint can be found on ArXiv here.
