000003818 520__ $$aSemileptonic B-meson decays allow for determining the magnitudes of the CKM matrix parameters Vcb and Vub, two fundamental parameters of the SM flavor sector. Belle II analyses use both exclusive decays such asB->D*lnu and B->pilnu, or inclusive X_clnu or X_ulnu final states restricted in phase space. The low-background collision environment, along with the possibility of partially or fully reconstructing one of the two B mesons in the event, offer precision on Vcb and Vub approaching that of world-best results.
