Abstract

Heavy Quark Expansions for semileptonic decays of beauty hadrons are briefly reviewed. I analyze how |V(cb)| can be extracted from the semileptonic width of B mesons, the average semileptonic width of all weakly decaying beauty hadrons and from B \ra l νD^* at zero recoil. Special attention is paid to present theoretical uncertainties (including correlations among them) and on how to reduce them in the future. Finally I will comment on theoretical uncertainties in |V(ub)/V(cb)|.
