Yangian Symmetry, S-Matrices and Bethe Ansatz for the AdS5 x S5 Superstring

We discuss the relation between the recently derived bound state S-matrices for the AdS5 x S5 superstring and Yangian symmetry. We will study the relation between this Yangian symmetry and the Bethe ansatz. In particular we can use it to derive the Bethe equations for bound states.
