摘要：

We present preliminary results from simulations done on 170 32(3) x 64 lattices at beta = 6.0 using quenched Wilson fermions. This talk focuses on the Q(2) behavior of the form-factors, extrapolation in quark masses, dependence on renormalization scheme, and comparison with heavy-quark effective theory (HQET). Even though we cannot estimate errors due to quenching and discretization, our results are consistent with experimental results for D decays. We present results for the Isgur-Wise function and estimate xi'(w = 1) = 0.97(6).
