We investigate the existence of chiral zero modes at a-1
hs/BQ2.GIF>1 GeV in quenched domain-wall QCD. Simulations are carried out for the plaquette and an RG-improved gauge actions on a 123 × 24 × Ns, lattice with Ns = 10 − 50. We find that the pion mass in the chiral limit remains non-vanishing as Ns → ∞ for both gauge actions. Possible origins of this non-vanishing pion mass are discussed.
