| Title | Charmed-meson decay constants in three-flavor lattice QCD |
| Date | 2005-09 |
| Description | We present the first lattice QCD calculation with realistic sea quark content of the D+-meson decay constant fD+. We use the MILC Collaboration's publicly available ensembles of lattice gauge fields, which have a quark sea with two flavors (up and down) much lighter than a third (strange). We obtain fD+ = 201 + 3 + 17 MeV, where the errors are statistical and a combination of systematic errors. We also obtain fDs = 249 + 3 + 16 MeV for the Ds meson. |
