The static quark potential in 2+1 flavour Domain Wall QCD from QCDOC
Abstract
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

lattice with fifth dimension size 8. We also examine size of discretization error from scaling of a pair of dimensionless quantities,

and

, and found small scaling violation.
