Charmed meson spectra and decay constants with one-loop $O(a)$ improved relativistic heavy quark action

Y. Kayaba, S. Aoki, M. Fukugita +8

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 $a…
