We discuss the very different roles of the valence-quark and the sea-quark residual masses (m v res and m s res) in dynamical domain-wall fermions simulations. Focusing on matrix elements of the effective weak hamilto-nian containing a power divergence, we find that m v res can be a source of a much bigger systematic error. To keep all systematic errors due to residual masses at the 1% level, we estimate that one needs am s res < ∼ 10 −3 and am v res < ∼ 10 −5 , at a lattice spacing a ∼ 0.1 fm… CONTINUE READING
