Title: Precise Charm to Strange Mass Ratio and Light Quark Masses from Full Lattice QCD

Abstract

By using a single formalism to handle charm, strange, and light valence quarks in full lattice QCD for the first time, we are able to determine ratios of quark masses to 1%. For m{sub c}/m{sub s} we obtain 11.85(16), an order of magnitude more precise than the current PDG average. Combined with 1% determinations of the charm quark mass now possible this gives m{sub s}(2 GeV)=92.4(1.5) MeV. The MILC result for m{sub s}/m{sub l}=27.2(3) yields m{sub l}(2 GeV)=3.40(7) MeV for the average of u and d quark masses.
