Abstract

We present our lattice calculation of the semileptonic form factors for the decays

D \to K^{*}

,

D_{s} \to θ

, and

D \to ρ

using Wilson fermions on a

24^{3}

× 39 lattice at

β = 6.0 with 8

quenched configurations. For

D \to K^{*}

, we find for the ratio of axial form factors

\frac{A_{2} (0)}{A_{1}} (0) = 0.70 \pm {0.16}_{- 0.15}^{+ 0.20}

. Results for other form factors and ratios are also given.
