abstract

We report on a study of the light hadron spectroscopy
in QCD with two flavors of dynamical quarks
using the plaquette gauge action and
the non-perturbatively $O(a)$ improved Wilson quark action.
Simulations are carried out on a $16^3 \times 48$ lattice
at $\beta=5.2$ with 5 sea quark masses corresponding to
$m_{\rm PS}/m_{\rm V} \simeq 0.8$--0.6.
We focus particularly on the results for the meson and quark
masses and discuss the effect of sea quarks on these observables.
