\section{Preselection yields}

| 2 |
\label{sec:yields}
|

|
| 4 |
The data yields and the MC predictions are given in Table~\ref{tab:yields}.
|
| 5 |
The MC yields are normalized to 34.85 pb$^{-1}$ using the cross-sections
|
| 6 |
from Reference~\cite{ref:xsec}.
|
| 7 |
As anticipated, the MC predicts
|
| 8 |
that the preselection is dominated by $t\bar{t}$. The data yield is
|
| 9 |
in good agreement with the prediction.
