Charmonium, $D_s$ and $D_s^*$ from overlap fermion on DWF configurations

, 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

D_s

,

D_s^*

and

J/\psi

as inputs and obtain

m_c^{\overline{\rm MS}}(2\,{\rm GeV})=1.110(24)\,{\rm GeV}

,

m_s^{\overline{\rm MS}}(2\,{\rm GeV})=0.104(9)\,{\rm GeV}

and

r_0=0.458(11)\,{\rm fm}

. Subsequently, the hyperfine-splitting of charmonium and

f_{D_s}

are predicted to be

112(5)\,{\rm MeV}

and

254(5)\,{\rm MeV}

, respectively.
