摘要：

We present our lattice calculation of the semileptonic form factors for the decays D --> K*, D(s) --> phi, and D --> rho using Wilson fermions on a 24(3) x 39 lattice at beta = 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.
