%High cross section new physics signals are likely to be produced |
| 12 |
|
%strongly; thus, we expect significant hadronic activity in conjunction with the two leptons. |
| 13 |
|
%by adding the following two requirements to the preselection described above: |

|
| 15 |

To look for possible BSM contributions, we define 2 signal regions that preserve about |
| 16 |
– |
0.1\% of the dilepton $t\bar{t}$ events, by adding requirements of large \MET\ and \Ht: |
| 17 |
– |
|
| 18 |
– |
\begin{itemize} |
| 19 |
– |
\item high \MET\ signal region: \MET $>$ 275~GeV, \Ht $>$ 300~GeV |
| 20 |
– |
\item high \Ht\ signal region: \MET $>$ 200~GeV, \Ht $>$ 600~GeV |
| 21 |
– |
\end{itemize} |

For the high \MET\ (high \Ht) signal region, the MC predicts 2.6 (2.5) SM events, |
| 24 |
– |
dominated by dilepton $t\bar{t}$; the expected LM1 yield is 17 (14) and the |
| 25 |
– |
expected LM3 yield is 4.3 (4.3). |
