Leptonic Decays of B- and D-Mesons
R. Sommer
Abstract
The present status of lattice calculations of fD, fB and some mass splittings are discussed. When one includes the uncertainties due to discretization errors, the results do not yet have a sufficient precision to be relevant to phenomenological applications. There are, however, good prospects of cutting down the uncertainties by a factor of 2 or more soon.
