摘要：We present results for light meson masses and psedoscalar meson decay constants in 2+1 flavour
domain wall QCD with the DBW2 and Iwasaki gauge actions, using lattices with linear sizes in
the range 1.6 to 2.2fm and u and d quark masses as low as one quarter of the strange quark mass.
All data were generated on the QCDOC machines at the University of Edinburgh and Brookhaven
National Laboratory. Despite large residual masses and a limited number of sea quark mass values
with which to perform chiral extrapolations, our results agree with experiment and scale within
errors.
