Description
We present light pseudoscalar physics in the continuum limit of
2+1 flavour domain wall QCD by the RBC and UKQCD collaborations.
We make use of a fermion action with good chiral symmetry
and use two different lattice spacings.
We use a new approach to match ensembles within the range of
simulated masses, and apply a simultaneous chiral and continuum
extrapolation. We present continuum results for pion and kaon decay
constants, f_K/f_pi, quark masses and the neutral kaon mixing parameter
B_K. We discuss the systematic errors arising from the choices in
the analysis.
