摘要：Preliminary results for the light baryon spectrum computed in an on-going QCD simulation using
2+1 flavors of domain wall fermions and the Iwasaki gauge action are presented and discussed.
Lattice sizes 24364 and 32364 with spacings 0.114 and 0:08 fm are used in the calculation.
The physical spatial size is thus 2.74 fm and 2:6 fm, respectively. The degenerate light quarks
have masses down to 0:13, in units of the physical strange quark mass. We present preliminary
fits of the nucleon mass, including next-to-leading order heavy baryon chiral perturbation theory,
which works reasonably well.
