Light Quark Masses with Dynamical Wilson Fermions

Abstract

We determine the masses of the light and the strange quarks in the $\overline{MS}$-scheme using our high-statistics lattice simulation of QCD with dynamical Wilson fermions. For the light quark mass we find $m_{\overline{MS}}^{light}(2GeV)=2.7(2)MeV$, which is lower than in quenched simulations. For the strange quark, in a sea of two dynamical light quarks, we obtain $m_{\overline{MS}}^{strange}(2GeV)=140(20)MeV$.
