The data yields and corresponding MC predictions after this event preselection |

|
are given in Table~\ref{tab:yields}. The MC yields are normalized to~\lumifinal\ using |

|
next-to-leading order (NLO) cross sections. At the current LHC luminosity, the mean |

number of expected pile-up interactions is approximately 5. In the MC, pile-up interactions |

number of interactions in a single beam crossing is approximately 5. In the MC, multiple interactions |
| 8 |
|
are superimposed on the hard collision, and the MC is reweighted such that the distribution |

|
of reconstructed primary vertices matches that in data. As expected, the MC predicts that the |

sample passing the preselection is dominated by dilepton $t\bar{t}$. The data yield is in |
