Abstract

We investigate mesons containing charm quarks on fine lattices with a^{-1} $\sim$ 5 GeV. The quenched approximation is employed using the Wilson gauge action at $\beta$ = 6.6 and nonperturbatively O(a) improved Wilson quarks. We present results for decay constants using various interpolating fields and give preliminary results for form factors of semileptonic decays of D_s mesons to light pseudoscalar mesons.
