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 benhoob 1.4 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8     %{\bf FIXME: UPDATE TO 5.1/fb VTX-REWEIGHTING, CURRENTLY USING OUTDATED FUNCTION}.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 benhoob 1.1 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.

188 benhoob 1.2 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 benhoob 1.6 \item Veto events containing a third selected lepton (electron or muon) with \pt $>$ 10 GeV;
193 benhoob 1.2 \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 benhoob 1.4 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.
