The charmed-strange meson spectrum from overlap fermions on domain wall dynamical fermion configurations
Abstract
The charmed-strange meson spectrum is calculated with the overlap valence fermions on 2+1 flavor domain wall dynamical configurations for 323× 64 lattices with a spatial size of 2.7 fm. Both charm and strange quark propagators are calculated with the overlap fermion action. The calculated scalar meson at 2304(22) MeV and axial-vector meson at 2546(27) MeV are in good agreement with the experimental masses of Ds0*(2317) and Ds1(2536).
