This analysis uses the same data and Monte Carlo (MC) samples used in~\cite{baseline}. Table~\ref{tab:data} summarizes relevant details of the combined $2.1\rm~fb^{-1}$ dataset we analyze. {\bf need to replace PR's with oct3,and jul5, add the 2010 data back in}. We model processes that contribute to our signal region with the MC samples listed in Table~\ref{tab:mc}. The first and second rows of this table list samples used directly for signal extraction or background estimation. The cross sections and branching ratios used for Higgs signal processes are taken from the CERN Yellow Report~\cite{Yello}. Samples given in the last row of Table~\ref{tab:mc} are not used for direct yield estimation. Instead, we use these samples in cross-checks of data-driven background estimates and for shape studies when we lack sufficient data. |

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 estaimte shapes 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 all samples to the vertex multiplicity distribution measured in data. |
