Abstract
We present a new integrable model for correlated electrons which is based on a symmetry. By using an -pairing realization we construct eigenstates of the Hamiltonian with off-diagonal long-range order. It is also shown that these states lie in the ground state sector. We exactly solve the model on a one-dimensional lattice by the Bethe ansatz.
