Measurement of R = \boldmath$\mathcal{B}(t\to Wb)/\mathcal{B}(t\to Wq)$ in Top--quark--pair Decays using Lepton+jets Events and the Full CDF Run II Data set

CDF Collaboration

We present a measurement of the ratio of the top-quark branching fractions $R=\mathcal{B}(t\to Wb)/\mathcal{B}(t\to Wq)$, where $q$ represents quarks of type $b$, $…
