Description
We present results for the low-lying spectrum of D and D_s mesons from
a lattice QCD calculation on 2+1 flavor Clover-Wilson configurations
generated by the PACS-CS collaboration. In particular S- and P-wave
states of charmed and charmed-strange mesons are explored for pion
masses down to 156MeV. For the heavy quark, the Fermilab method is
employed. In addition to ground states, some excited states are
extracted using the variational method. To check our setup, calculations of the charmonium spectrum are also carried out. For charmonium, the low-lying spectrum agrees favorably with experiment. For heavy-strange and heavy-light systems substantial differences in comparison to experiment values remain in channels with nearby scattering states.
