We currently use the same data and Monte Carlo (MC) samples that are used in~\cite{ref:baseline}. The specific samples are listed in Tables~\ref{tab:data} and~\ref{tab:mc}. For data, we intend to add acceptance by including the single lepton triggers and dilepton cross-triggers. |

We analyze $4.7\rm~fb^{-1}$ of 2011 data in this analysis. We select events from the \verb|DoubleElectron| and \verb|DoubleMuon| datasets that pass the lowest-threshold, unprescaled double-lepton trigger available in a given run. The triggers used and the run ranges we consider are listed in Tables~\ref{tab:dataele} and~\ref{tab:datamu}. |

The first and second rows of Table~\ref{tab:MC} list samples of Monte Carlo (MC) events used for signal extraction and background estimation. We employ $17$ sets of simulated Higgs samples corresponding to mass hypotheses between $115\rm~GeV/c^{2}$ and $600\rm~GeV/c^{2}$. Higgs cross sections, branching ratios and their uncertainties are taken from the CERN Yellow Report~\cite{Yello}. The last row of Table~\ref{tab:MC} lists MC samples that we use to cross-check data-driven background estimates and to obtain shapes estaimtes when sufficient data is lacking. All samples in Table~\ref{tab:MC} were produced with \verb|S4_START42_V11| conditions as part of the \verb|Summer11| campaign. We reweight events from these samples to the vertex multiplicity distribution measured in data. |
