First measurement of B(t -\> Wb)/B(t -\> Wq) in the dilepton channel in pp collisions at sqrt(s)=7 TeV
The flavor content of $t \bar{t} \rightarrow (l^{+}\nu q)(l^{-}\bar{\nu} \bar{q})$ events is studied using a sample corresponding to an integrated luminosity of 2.2~fb$^{-1}$ of proton-proton collisions produced at $\sqrt{s}=$7~TeV and acquired by the CMS detector. Data-driven strategies are used to...
