The datasets used for this analysis are summarized in |

Tables~\ref{tab:DatasetsData} (data) and~\ref{tab:DatasetsMC} (MC). |
| 4 |

The total integrated luminosity is \lumi after |
| 5 |

applying the official good run list. The main Monte Carlo |
| 6 |

samples are generated with Madgraph, though samples with |
| 7 |

alternative generators such as Powheg and MC@NLO are also used for |
| 8 |

the derivation of systematic uncertainties in the \ttbar~background prediction. |
| 9 |

The triggers used to select both the signal and control samples are |
| 10 |

also summarized in Table.~\ref{tab:TrigData}. |

We use the same datasets, triggers, and MC samples as in SUS-11-021. Details can be found in AN-2011/464. |
| 8 |
– |
We use a combination of rereco and prompt reco for both signal and control data samples. % leptons and photons. |
| 9 |
– |
This data covers the entire Run2011A and Run2011B data taking periods, |
| 10 |
– |
and the integrated luminosity corresponds to \lumi. |
| 11 |
– |
We select signal events passing one of a set of ee, e$\mu$ or $\mu\mu$ dilepton triggers. |
| 12 |
– |
A control sample of \gjets\ events is selected using a set of single photon triggers with varying |
| 13 |
– |
photon \pt\ thresholds. |
| 14 |
– |
Summer11 monte carlo samples are used. |

For selecting the dilepton sample, the following datasets are used (the pythia DY samples are used only for generator level Z mass values less than 50 to avoid overlap with the madgraph DYJets sample), including the benchmark SUSY points LM4 and LM8: |
