Light hadron spectrum and quark masses in $N_f=2$ full QCD from CP-PACS

Abstract: We present the final results of a light hadron spectrum calculation in full QCD with $N_f=2$ dynamical quarks on CP-PACS using an RG-improved gluon action and the tadpole improved SW quark action. Four sea quark masses corresponding to $m_{\rm PS}/m_{\rm V} \sim 0.8$--0.6 are simulated on lattices with a spatial side length of $2.4~{\rm fm}$, with 3 different lattice spacings $a=0.10,\ 0.15,\ 0.20$~fm. We report results for the light hadron and quark masses and make a comparison with those obtained in quenched QCD with the same quark and gluon actions.
