Probing the Heavy Flavor Content in $t\overline{t}$ Events and Using $t\overline{t}$ Events as a Calibration Tool at CMS

We present two analyses dedicated to measure the ratio of branching ratios of the top quark, R=B(t->Wb)/(t->Wq) (where q=d,s,b), using ttbar events with either one or two prompt isolated leptons (e or mu) in the final state. Furthermore the framework of the dileptonic analysis was used also fo...

description We present two analyses dedicated to measure the ratio of branching ratios of the top quark, R=B(t->Wb)/(t->Wq) (where q=d,s,b), using ttbar events with either one or two prompt isolated leptons (e or mu) in the final state. Furthermore the framework of the dileptonic analysis was used also for a feasibility study of the measurement of b-tagging efficiency, by assuming the R value to be the Standard Model one. Data-driven techniques to control the background in the selected events are discussed and the expected simulation results are presented.
