They focus on the determination of the CKM matrix elements |V_{ub}| and |V_{cb}| in inclusive and exclusive b --> u l nu and b--> c l nu decays, and on form factors measurement in exclusive c--> s l nu decays.4 pages, 1 figure, contributed to the proceedings of QCD 08 Montpellier, France, 7-12th July 2008High Energy Physics - Experimenttext
