Exploratory study of the Ds spectrum in 2+1 Domain Wall QCD with heavy overlap
Abstract
We present preliminary results for the Ds meson spectroscopy study on the 2+1 flavour domain wall fermion lattice configurations, generated with the Iwasaki gauge action at beta=2.13 by the RBC-UKQCD collaboration. The simulations are on 163×32 lattice with Ls=16. We consider the charm quark propagating as an overlap fermion at fixed lattice spacing. The dispersion relation and mass splittings are evaluated.
