Abstract
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 24 3 64 and 32 3 64 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.
