The RTT-Realization for the Deformed gl(2|2) Yangian
Niklas Beisert, Marius de Leeuw
In this paper we work out the RTT-realization for the Yangian algebra of the Hubbard model and AdS/CFT correspondence. We find that this Yangian algebra is of a non-standard type i…

On Yangian-invariant regularisation of deformed on-shell diagrams in N=4 super-Yang-Mills theory
Niklas Beisert, Johannes Broedel, Matteo Rosso
We investigate Yangian invariance of deformed on-shell diagrams with D=4, N=4 superconformal symmetry. We find that invariance implies a direct relationship between the deformation…
