Scientific paper

We present the results of a calculation of semileptonic form factors of D and
B mesons. The calculation uses nonperturbatively order a improved quenched
lattice QCD and two values of the coupling. Results for charm mesons show
reasonable agreement with experiment. The lattice results for B -> rho l nu are
compared with high q^2 experimental results.
