Charmed Strange mesons from Lattice QCD with Overlap Fermions

Understand

The charmed-strange meson masses are calculated on a quenched lattice QCD.

• The charm and strange quark propagators are calculated on the same lattice with the overlap fermion.
• $16^3\times 72$ lattice with Wilson gauge action at $\beta=0.6345$ are used.
• The charm and strange quark masses are determined by fitting the $J/\psi$ and $\phi$ masses respectively.
