%\subsection{Datasets} |

> |
In this section we list the datasets, triggers, and MC samples used in the analysis. For selecting signal |
| 7 |
> |
events, we use dilepton triggers in the DoubleElectron, DoubleMu, and MuEG datasets. |
| 8 |
> |
An event in the ee final state is required to pass the dielectron trigger, a |
| 9 |
> |
$\mu\mu$ event is required to pass the dimuon trigger, while an e$\mu$ event is required to pass at least one |
| 10 |
> |
of the two $e-\mu$ cross triggers. The efficiencies of the ee, $\mu\mu$ and e$\mu$ triggers with respect to the |
| 11 |
> |
offline selection have been measured as $0.95\pm0.03$, $0.88\pm0.03$, and $0.92\pm0.03$, respectively~\cite{ref:SSAN}. |
| 12 |
> |
These trigger efficiencies were measured with the first 5.1 fb$^{-1}$ and will be updated with the full data sample. |
| 13 |
> |
Preliminary measurements of the trigger efficiency with the full sample show consistent results within $\sim1-2$\%. |
| 14 |
> |
A sample of \gjets\ events, used as a control sample to estimate the \zjets\ |
| 15 |
> |
background, is selected using a set of single photon triggers. |
| 16 |
> |
The golden prompt reco json corresponding to \lumi is used. |
| 17 |
> |
%The golden json of Aug 31st, corresponding to an integrated luminosity of 9.7 fb$^{-1}$, is used as the starting point. |
| 18 |
> |
%However, due to a bug in the Run2012C-PromptReco-v1 data samples (corresponding to 0.5 fb$^{-1}$), this portion of the data |
| 19 |
> |
%is currently excluded but will be added back after it is reprocessed. Thus we currently use a sample corresponding to \lumi. |
| 20 |
> |
%All data and MC samples are processed in CMSSW\_5\_3\_2\_patch4. |

We use the same datasets, triggers, and MC samples as in SUS-11-021. Details can be found in AN-2011/464. |

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: |
