Abstract: (arXiv)
We report on an on-going two-flavor full QCD study on CP-PACS using an RG-improved gauge action and a tadpole-improved SW quark action. Runs are made for three lattice spacings a−1≈0.9a^{-1}\approx 0.9, 1.3, and 2.5 GeV on 123×2412^3\times24, 163×3216^3\times32, and 243×4824^3\times48 lattices. Four sea quark masses having mPS/mV≈0.8m_{\rm PS}/m_{\rm V} \approx 0.8--0.6 are simulated, for each of which hadron masses are evaluated for valence quark masses corresponding to mPS/mV≈0.8m_{\rm PS}/m_{\rm V} \approx 0.8--0.5. Results for hadron and light quark masses are presented and compared with those obtained in quenched QCD.
