Form factors in SU(3)-invariant integrable models    [PDF]

S. Belliard, S. Pakuliak, E. Ragoucy, N. A. Slavnov
We study SU(3)-invariant integrable models solvable by nested algebraic Bethe ansatz. We obtain determinant representations for form factors of diagonal entries of the monodromy matrix. This representation can be used for the calculation of form factors and correlation functions of the XXX SU(3)-invariant Heisenberg chain.
