摘要：We report our present status of on-going project on the measurement of the static quark potential
in 2+1 flavour domain wall QCD with various improved gauge actions and couplings. Lattice
spacing determined from Sommer scale on these ensembles are from 1.6 GeV to 2.0 GeV for
163 £32 lattice with fifth dimension size 8. We also examine size of discretization error from
scaling of a pair of dimensionless quantities, (r0mπ )2 and r0mρ , and found small scaling violation.
