First Measurement of the cross section ratio ttbb/ttjj in pp Collisions at sqrt{s
We present the first measurement of the cross section ratio $\sigma$($t\bar{t}b\bar{b}$)/$\sigma$($t\bar{t}jj$) in the dilepton decay mode, using a data sample corresponding to an integrated luminosity of $5~\rm{fb}^{-1}$ collected in pp collisions at $\sqrt{s}$ = 7 TeV with the CMS detector at the...
