Description
During past years plenty of unexpected symmetries have been revealed in the structure of perturbative scattering amplitudes. We formulate Yangian symmetry of amplitudes in N=4 super Yang-Mills theory in terms of eigenvalue relations for monodromy matrix operators. The Quantum Inverse Scattering Method provides us the appropriate tools to treat the extended symmetry and to recover as its consequences many known features like cyclic and inversion symmetry, BCFW recursion, Inverse Soft Limit construction, Grassmannian integral representation, R-invariants and on-shell diagram approach.
