New integrable variant of the one-dimensional Hubbard model with
variable-range correlated hopping is studied. The Hamiltonian is constructed by
applying the quantum inverse scattering method on the infinite interval at zero
density to the one-parameter deformation of the L-matrix of the Hubbard model.
By construction, this model has Y(su(2))⊕Y(su(2)) symmetry in the
infinite chain limit. Multiparticle eigenstates of the model are investigated
through this method.Comment: 25 pages, LaTeX, no figure
