Abstract

We explore the Gell-Mann-Okubo mass relation among the octet baryons using fully-dynamical, mixed-action (domain-wall on rootedstaggered) lattice QCD calculations at a lattice spacing of b similar to 0. 125 fm and pion masses of m pi similar to 290, 350, 490 and 590 MeV. Deviations from the Gell-Mann-Okubo mass relation are found to be small at each quark mass. (C) 2007 Elsevier B.V. All rights reserved.
