INSTANTONS, CHIRAL-SYMMETRY BREAKING AND THE FATE OF THE ULTIMATE QUENCHED CALCULATION

We investigate how topological zero-modes affect hadron physics in the quenched approximation. We remark that in a finite volume the exact zero-modes render the chiral condensate pathological and explain why this is not observed in lattice calculations. We then provide an argument, supported by a mo...
