Abstract
We report on our study of light hadron spectrum and quark masses in QCD wit h two flavors of dynamical quarks. Simulations are made with the plaquette gauge action and the non-perturbatively O(a) improved Wilson quark action. We simulate 5 sea qaurk masses corresponding to m(PS)/m(V) similar or equal to 0.8-0.6 at beta = 5.2 on 12(3) x 48, 16(3) x 48 and 20(3) x 48 lattices . A comparison with previous calculations in quenched QCD indicates sea qua rk effects in meson and quark masses.
