摘要：We investigate the charm quark system on 2+1 flavor PACS-CS configurations. Calculations are performed at the lattice spacing a1 =2:194(10) GeV and the spatial extent L=2:9 fm with O(a)- improved Wilson fermions for the light quarks and the relativistic heavy fermion for the charm quark. Our dynamical ud and strange quark masses and valence charm quark mass are set to their physical values. A comparison of the mass spectrum and decay constants with experiments is presented. Our results for the charm quark mass and CKM matrix elements are also reported.
