Description

We present our lattice calculation of the semileptonic form factors for the decays D→K*, Ds→φ, and D→ρ using Wilson fermions on a 243x39 lattice at β=6.0 with 8 quenched configurations. For D→K*, 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
