Probing the heavy flavor content in ttbar events and using ttbar events as a calibration tool at CMS
We present two analyses dedicated to measure the ratio of branching ratios of the top quark using ttbar events, $R=B(t \rightarrow W b )/(t \rightarrow W q )$ ( where $q=d,s,b$) with either one or two prompt isolated leptons (e or mu) in the final state. Data-driven techniques to control the backgro...
