Abstract

We present measurements of the chiral condensate and topological charge history for 2+1 flavour Domain Wall QCD, and compute spectral flows for the corresponding Hermitian Wilson Dirac operator. We considered several lattice spacings, with the DBW2 and Iwasaki gauge actions and different sea quark masses on a volume of 16³ × 32 and a fifth dimension of size 8. These results show the spectral structure on 2+1 flavours of DWF QCD. We also discuss the dependence of the tunneling rate on lattice spacing and gauge action. All data was generated on the QCDOC machines.
