| Resumen | We present a measurement of the ratio of top quark branching fractions R=B(t→Wb)/B(t→Wq), where q can be a d, s, or b quark, in the lepton+jets and dilepton tt̄ final states. The measurement uses data from 5.4fb-1 of pp̄ collisions collected with the D0 detector at the Fermilab Tevatron Collider. We measure R=0.90±0.04, and we extract the Cabibbo-Kobayashi-Maskawa (CKM) matrix element |Vtb| as |V tb|=0.95±0.02, assuming unitarity of the 3×3 CKM matrix. |
