Abstract
Elementary excitations in the one-dimensional Hubbard model with bound ary fields are discussed. Boundary scattering matrices for the excitat ions of the charge and spin sectors are evaluated. Both the repulsive and the attractive Hubbard models at half-filling and without a magnet ic held are studied.
