Resumen

The charmed-strange meson mases are calculated on a quenched lattice QCD. The charm and strange quark propagators are calculated on the same lattice with the overlap fermion. 16³ ×72 lattices with Wilson gauge action at β = 6.3345 are used. The charm and strange quark masses are determined by fitting the J/ψ and φ masses respectively. The charmed strange meson spectrum for the scalar, axial, pseudoscalar and vector channels are calculated. They agree with experiments. In particular, we find the scalar meson mass to be 2248(78) MeV which is in agreement with that of D^∗ _s ₀(2317).
