| Abstract |
We calculate charmed meson spectra and decay constants in lattice QCD employing one-loop O(a) improved heavy quark action and axial-vector currents. In quenched simulations at anot, vert, similar0.1 fm with the plaquette gauge action as well as a renormalization-group improved one, it is shown that the deviation from the continuum dispersion relation and the violation of space-time symmetry for the pseudoscalar meson decay constants are substantially reduced, once the O(a) improvement is applied. Preliminary results with two flavors of dynamical quarks are also presented.
