Abstract

We use a relativistic highly improved staggered quark action to discretize 
charm quarks on the lattice. We calculate the masses and the dispersion 
relation for heavy-heavy and heavy-light meson states, and show that the 
discretization errors are at the few percent level. We present our 
preliminary results on a precise calculation of $f_{D_s}$ and $f_D$, and 
we discuss the future prospects of this method.
