摘要：
We derive exactly scalar products and form factors for integrable higher-spin XXZ chains through the algebraic Bethe-ansatz method. Here spin values are arbitrary and different spins can be mixed. Transforming the symmetric R-matrix into the asymmetric one that is compatible with subalgebra U-q (sl(2))) of U-q ((sl(2)) over cap). we calculate the exact expressions by the representation theory of U-q (sl(2)). The results should be fundamental for calculating form factors and correlation functions systematically for various solvable models associated with the integrable XXZ spin chains.
