Scientific paper

We present a summary of our results for the light hadron spectrum in quenched lattice QCD and preliminary ones in two-flavor full QCD. For the quenched hadron spectrum we find that the mass formulae predicted by quenched chiral perturbation theory(QChPT) give a good description of our results. Employing the QChPT mass formulae for chiral extrapolations we conclude that the mass spectrum in the continuum limit deviates unambiguously and systematically from experiment. For our two-flavor full QCD results we focus on the dynamical quark effects on the light hadron spectrum.
