Scientific paper

We present preliminary continuum results for light hadronic quantities obtained by the RBC/UKQCD collaboration using domain wall fermions with both the Iwasaki and the novel Dislocation Suppressing Determinant Ratio (DSDR) gauge actions. The DSDR action allows us to simulate at near physical quark masses on a larger, coarser lattice (a^-1 = 1.4 GeV, L = 4.6 fm) while retaining good chiral symmetry properties. We discuss our ongoing combined analysis of the three ensemble sets and give early results for the pion and kaon decay constants, quark masses and B_K.
