Abstract

We determine the charmed meson decay constants in 2+1 flavor lattice QCD. We find fD+ = 201±3±17 MeV and fDs = 249±3±16 MeV where the errors are statistical and the combined systematic uncertainty. We simulate quarks as light as mq/ms = 0.1 and use NLO predictions of Chiral Perturbation Theory to control the extrapolation to the physical results. We study three lattice spacings in order to estimate the continuum limit. All of the results presented at Lattice 2005 appear in the publication: C. Aubin et al., "Charmed meson decay constants in three-flavor lattice QCD", Phys. Rev. Lett. 95, 122002 (2005), [arXiv: hep-lat/0506030].
