Query: Lattice QCD with Exponentially Small Chirality Breaking   A new multifermion formulation of lattice QCD is proposed. The model is free
of spectrum doubling and preserves all nonanomalous chiral symmetries up to
exponentially small corrections. It is argued that a small number of fermion
fields may provide a good approximation making computer simulations feasible.
