Abstract
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.
