Abstract

We take a new approach to determine the scale parameter r₀, the physical masses of strange and charm quarks through a global fit which incorporates continuum extrapolation, chiral extrapolation and quark mass interpolation to the lattice data. The charmonium and charm-strange meson spectrum are calculated with overlap valence quarks on 2+1-flavor domain-wall fermion gauge configurations generated by the RBC and UKQCD Collaboration. We use the masses of Ds, D s and J=y as inputs and obtain m^MS_c (2GeV) = 1:110(24)GeV, m^MS_c (2GeV) = 0:104(9)GeV and r₀= 0:458(11)fm. Subsequently, the hyperfine-splitting of charmonium and fD_s are predicted to be 112(5)MeV and 254(5)MeV, respectively.
