LATTICE ANALYSIS OF SEMILEPTONIC FORM-FACTORS

We present preliminary results from simulations done on 170 32(3) x 64 lattices at beta = 6.0 using quenched Wilson fermions. This talk focu ses on the Q(2) behavior of the form-factors, extrapolation in quark m asses, 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 e xperimental results for D decays. We present results for the Isgur-Wis e function and estimate xi'(w = 1) = 0.97(6).
