Le résumé fourni par la source

We present a measurement of the ratio of the top-quark branching fractions $R=\mathcal{B}(t\ensuremath{\rightarrow}Wb)/\phantom{\rule{0ex}{0ex}}\mathcal{B}(t\ensuremath{\rightarrow}Wq)$, where $q$ represents quarks of type $b$, $s$, or $d$, in the final state with a lepton and hadronic jets. The measurement uses $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ proton-antiproton collision data from $8.7\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of integrated luminosity collected with the Collider Detector at Fermilab during Run II of the Tevatron. We simultaneously measure $R=0.94\ifmmode\pm\else\textpm\fi{}0.09$ ($\mathrm{stat}+\mathrm{syst}$) and the $t\overline{t}$ production cross section ${\ensuremath{\sigma}}_{t\overline{t}}=7.5\ifmmode\pm\else\textpm\fi{}1.0\text{ }(\mathrm{stat}+\mathrm{syst})\text{ }\text{ }\mathrm{pb}$. The magnitude of the Cabibbo-Kobayashi-Maskawa matrix element, $|{V}_{\mathrm{tb}}|=0.97\ifmmode\pm\else\textpm\fi{}0.05$ ($\mathrm{stat}+\mathrm{syst}$) is extracted assuming three generations of quarks, and a lower limit of $|{V}_{\mathrm{tb}}|>0.89$ at 95% credibility level is set.
