Abstract:
We consider an $XYZ$ spin chain within the framework of the generalized algebraic Bethe ansatz. We study form factors of local operators corresponding to singlet states in the free-fermion limit. We obtain explicit representations for these form factors.
Keywords:generalized algebraic Bethe ansatz, Bethe vectors, scalar products,
form factors.
