Abstract
We determine the masses of the light and the strange quarks in the MS- scheme using our high-statistics lattice simulation of QCD with dynami cal Wilson fermions. For the light quark mass we find m light/MS (2GeV ) = 2.7(2) MeV, which is lower than in quenched simulations. For the s trange quark, in a sea of two dynamical light quarks, we obtain m stra nge/MS (2GeV) = 140(20) MeV. (C) 1997 Elsevier Science B.V.
