Full QCD light hadron spectrum from the CP-PACS

We report on an on-going two-flavor full QCD study on CP-PACS using an RG-i mproved gauge action and a tadpole-improved SW quark action. Runs are made for three lattice spacings a(-1) approximate to 0.9, 1.3, and 2.5 GeV on 12 (3) x 24, 16(3) x 32, and 24(3) x 48 lattices. Four sea quark masses having m(PS)/m(V) approximate to 0.8-0.6 are simulated, for each of which hadron masses are evaluated for valence quark masses corresponding to m(PS)/m(V) a pproximate to 0.8-0.5. Results for hadron and light quark masses are presen ted and compared with those obtained in quenched QCD.
