Abstract
From the experimental branching ratios for B--->rho0l-nu(l)BAR and D+- ->K0BAR(K0BAR)e+nu(e) one finds, in the heavy quark limit of HQET, \V (bu)\ = (8.1+/-1.7) x 10(-3), larger but consistent with the actual qu oted range (2-7) x 10(-3). In the same framework one predicts for R(B- ->Kgamma)=(2+/-2)10(-2).
