Light quark masses from the lattice

/ Abstract
Abstract A completely non-perturbative estimate is given for the u d and strange quark masses in quenched QCD using O(a) improved fermions and, for comparison, Wilson fermions. For improved fermions we find m u d MS (μ = 2 GeV ) = 4.4(2) MeV , m s MS (μ = 2 GeV ) = 105(4) MeV when using r0 to set the physical scale.
