Semileptonic decays of D, B, K mesons and the full CKM matrix from unquenched lattice QCD

We use lattice QCD to fully determine,the CKM matrix. [V-cd], [V-cs], [V-ub], [V-cb], and [V-us] are, respectively, directly determined with our lattice results for form factors of semileptonic D -> pi lv, D -> Klv, B -> pi lv, B -> Dlv and K -> pi lv decays. The accuracy is comparable to that of the Particle Data Group averages. In addition, [V-ud], [V-tb], [V-ts] and [V-td] are determined by using unitaxity of the CKM matrix and the experimental result for sin(2 beta). In this way, we obtain all 9 CKM matrix elements, where the only theoretical input is lattice QCD.
