Abstract

We present a high statistics study of the D- and B-meson decay constants. The results were obtained by using the Clover and Wilson lattice actions at two different values of the lattice spacing $a$, corresponding to $\beta=6.0$ and 6.2. After a careful analysis of the systematic errors present in th...
