Abstract

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.
