Abstract
The form of various Nambu-Jona-Lasinio terms in Hamiltonian lattice gauge theory is studied. The complete set of four-fermion interactions which recover full chiral invariance in their naive continuum limit are determined for staggered lattice fermions in 2+1 and 3+1 dimensions. We find that the standard four-fermion interaction traditionally used in lattice calculations does not belong to this set.
