Abstract

We determine the leptonic decay constants f_Ds and f_D in three flavor unquenched lattice QCD. We use O(a²)-improved sraggered light quarks and O(a)-improved charm quarks in the Fermilab heavy quark formalism. Our preliminary results, based upon an analysis at a single lattice spacing, are f_Ds = 263_-9⁺⁵ ± 24 MeV and f_D = 225_-13⁺¹¹ ± 21 MeV. In each case, the first reported error is statistical while the second is the combined systematic uncertainty.
