| description | The possibility of measuring $R=B(t\rightarrow Wb)/B(t\rightarrow Wq)$ %the branching fraction of the top quark to a W boson and a $b$~quark,
and the efficiency to tag $b$~quark jets ($b$-tagging),
in the top dilepton channel with $e\mu$ final states is discussed.
The heavy flavor content of the \ttbar events is studied, and a strategy to understand the background contributions to this measurement from data is outlined.
The uncertainties on the measurement are estimated for different $b$-tagging working points and for an integrated luminosity of 250~pb$^{-1}$ in proton-proton collisions at $\sqrt{s}=10$~TeV. |
