Probing the chiral limit of m_pi and f_pi in 2+1 flavor QCD with domain wall fermions from QCDOC

Abstract

We present results for the pseudoscalar meson masses and decay constants on 2+1 flavor DWF configurations with different sea quark masses and an inverse lattice spacing of 1.6(1) GeV, with a focus on chiral fits at small quark masses. The calculation is done on 16^3x32x8 lattices generated with the DBW2 gauge action.
