Furthermore, we obtain an upper bound for the residual mass in lattice QCD with the optimal domain-wall fermion. © 2012 American Physical Society.Chiral symmetry and the residual mass in lattice QCD with the optimal domain-wall fermionjournal article10.1103/PhysRevD.86.0945082-s2.0-84869019067WOS:000310868700004
