1 claudioc 1.1 \section{Preselection yields}
2     \label{sec:yields}
3    
4     The data yields and the MC predictions are given in Table~\ref{tab:yields}.
5 benhoob 1.13 The MC yields are normalized to 34.0~pb$^{-1}$ using the cross-sections
6 benhoob 1.14 from Reference~\cite{ref:xsec}. As anticipated, the MC predicts that the
7     preselection is dominated by $t\bar{t}$. The data yield is in good agreement
8     with the prediction. Also shown are the yields for LM0 and LM1, two of the LM
9     points which are benchmarks for SUSY analyses at CMS. Note that the LM yields
10     are calculated at NLO using process-dependent k-factors computed from Prospino.
