Query: Exactly integrable family of generalized Hubbard models with twisted
  Yangian symmetry   A strongly correlated electron system with controlled hopping, in the line of
the recently proposed generalized Hubbard models as candidates for high
T_c-superconductors, is considered. The model along with a whole class of such
systems are shown to be completely integrable with explicit quantum R-matrices
and the Lax operators. Inspite of novelties in the Bethe ansatz solution, the
final results do not deviate much from those of the standard Hubbard model.
  However, the symmetry of the model is changed to a recently discovered
twisted Yangian symmetry.
