Abstract:

We report results (on an intermediate statistics sample) of a study of weak semi-leptonic formfactors of

B

and

D

decays, addressing the uncertainties from mass extrapolations to chiral and to heavy quarks. Moreover, we present a nonperturbative test to the LMK current renormalization scheme for vector current {\it transition} matrix elements and find remarkable agreement.
