Abstract

We present our lattice calculation of the semileptonic form factors for the decays DK*, Ds, and D using Wilson fermions on a 243 × 39 lattice at =6.0 with 8 quenched configurations. For DK*, we find for the ratio of axial form factors A2(0)A1(0)=0.70±0.16-0.15+0.20. Results for other form factors and ratios are also given.
