3 \section{Data vs. MC Comparison in Preselection Region}
4 \label{sec:yields}
5
6 In this section we compare the data and MC samples passing the selection described in Sec.~\ref{sec:eventSelection}
7 In the following, the MC is reweighted to match the data distribution of number of reconstructed primary vertices.
8 %{\bf FIXME: UPDATE TO 5.1/fb VTX-REWEIGHTING, CURRENTLY USING OUTDATED FUNCTION}.
9 The trigger efficiencies of Sec.~\ref{sec:datasets} are applied. In all plots, the last bin contains the overflow.
10
11 We begin by counting the inclusive Z yields. Here we require the presence of two selected leptons without
12 any additional requirements on jets or \MET. In Fig.~\ref{fig:dilmass} the distribution of dilepton invariant
13 mass in the ee and $\mu\mu$ channels is displayed. In Table~\ref{table:zyields} the yields for selected dilepton
14 events in the Z mass window are indicated. Good data vs. MC agreement is observed, within the systematic uncertainties
15 of integrated luminosity (4.5\%), trigger efficiency (3\%), \zjets\ and \ttbar\ cross sections.

92 We next define the preselection region for the inclusive search using the following requirements:
93 \begin{itemize}
94 \item Number of jets $\geq$ 2;
95 \item Same flavor dileptons (opposite flavor yields will be shown since they are used in data for the FS background estimation);
96 \item Dilepton invariant mass $81<m_{\ell\ell}<101$ GeV.
97 \end{itemize}
98
99 The dilepton mass distributions in the preselection region of the inclusive search (without the dilepton mass requirement applied)
100 for the ee and $\mu\mu$ final states are shown in Figure~\ref{fig:dilmass_2j}. In Table~\ref{table:zyields_2j} the data and MC yields
101 in the inclusive preselection region are indicated. Good data vs. MC agreement is observed.

188 We next define the preselection region for the targeted search by adding the following requirements:
189 \begin{itemize}
190 \item Veto events containing a b-tagged jet;
191 \item Dijet invariant mass $70<m_{jj}<110$ GeV;
192 \item Veto events containing a third selected lepton (electron or muon) with \pt $>$ 10 GeV;
193 \end{itemize}
194
195 The rejection of events with a b-tagged jet strongly suppresses the \ttbar\ background, which is the dominant background in the inclusive search
196 after requiring large \MET. The requirement that the jet pair is consistent with originating from W/Z decay is motivated by the fact that we are
197 searching for signatures producing V(jj)Z($\ell\ell$)+\MET; this requirement suppresses the \zjets\ and \ttbar\ backgrounds. The veto of events
198 containting a third electron or muon suppresses the WZ background, and also serves to make this analyis exclusive with respect to searches in
199 the trilepton final state.
200
201 The dilepton mass distributions in the preselection region of the targeted search (without the dilepton mass requirement applied)
202 for the ee and $\mu\mu$ final states are shown in Figure~\ref{fig:dilmass_2j_targeted}. In Table~\ref{table:zyields_2j_targeted}
203 the data and MC yields in the preselection region are indicated. Good data vs. MC agreement is observed.
204 We also show the distribution of dijet mass in the targeted preselection (with the requirement on this quantity removed) in Fig.~\ref{fig:mjj},
205 which demonstrates that the MC does a reasonable job of modeling this quantity.
