23 >  \item $\pt>30~\GeVc$  and $|\eta|<1.4442 (2.1)$ for electrons (muons). The restriction to the barrel for electrons
24 > is motivated by an observed excess of events with large \mt\ with endcap electrons in the b-veto control region,
25 > and does not significantly reduce the signal acceptance since the leptons tend to be central.
26    \item muon ID criteria is based on the 2012 POG recommended tight working point

28 >  \item PF-based isolation ($\Delta R < 0.3$) relative isolation $<$ 0.15 and absolute isolation $<$ 5~GeV. PU corrections

30    \item $|\pt(\rm{PF}_{lep}) - \pt(\rm{RECO}_{lep})| < 10~\GeV$
31 <  \item $E/p_{in} < 4$ (electrons only)

40      within $|\eta|<2.5$ out of which at least 1 satisfies the CSV

42 <  \item require moderate $\met>50~\GeV$

280 + \subsection{Lepton Selection Efficiency Measurements}
281 + \label{sec:lepEff}
282 +
283 + In this section we measure the identification and isolation efficiencies for muons and electrons in data and MC using tag-and-probe studies.
284 + The tag is required to pass the full offline analysis selection and have \pt\ $>$ 30 GeV, $|\eta|<2.1$, and be matched to the single
285 + lepton trigger, HLT\_IsoMu24(\_eta2p1) for muons and HLT\_Ele27\_WP80 for electrons.
286 + The probe is required to have $|\eta|<2.1$ and \pt\ $>$ 20 GeV. To measure the identification efficiency we require the probe to pass the isolation requirement,
287 + to measure the isolation efficiency we require the probe to pass the
288 + identification requirement.
289 +
290 + The tag-probe pair is required to have opposite-sign and an invariant mass in the range 76--106 GeV.
291 + In order to suppress lepton pairs from sources other than Z boson
292 + decays, we require the event to have \met\ $<$ 30 GeV and no b-tagged
293 + jets (CSV loose working point).
294 +
295 + The muon efficiencies are summarized in Table~\ref{tab:mutnpeff} for inclusive events (i.e. no jet requirements). These efficiencies are displayed in Fig.~\ref{fig:mutnpeff} for
296 + several different jet multiplicity requirements.
297 + We currently observe good agreement for muons with \pt\ up to about 300 GeV.
298 + For high \pt\ muons we observe a source of background in the data with large impact parameters, which we suppress by requiring muon $d_0<0.02$~cm and $d_Z<0.5$~cm.
299 + %For muons with \pt\ $>$ 200 GeV the data efficiency
300 + %begins to drop, and the effect is especially pronounced for muons with \pt\ $>$ 300 GeV.
301 + We are currently investigating the source of this inefficiency.
302 + The electron efficiencies are summarized in Table~\ref{tab:eltnpeff} for inclusive events (i.e. no jet requirements). These efficiencies are displayed in Fig.~\ref{fig:eltnpeff}
303 + for several different jet multiplicity requirements. In general we observe good agreement between the data and MC identification and isolation efficiencies.
304 +
305 + % Pending a better understanding of the very high \pt\ muon efficiency,
306 + We
307 + do not correct the MC for differences in lepton efficiency.  In the
308 + background calculation, we do not take any systematics due to lepton
309 + selection
310 + efficiency uncertainties.  This is because all backgrounds except the
311 + rare MC background are normalized to the $M_T$ peak, thus the lepton
312 + identification uncertainty cancels out.  For the rare MC these
313 + uncertainties
314 + are negligible compared to the assumed cross-section uncertainty
315 + (Section~\ref{sec:bkg_other}).

584   In this section we measure the efficiencies of the single lepton triggers, HLT\_IsoMu24(\_eta2p1) for muons and HLT\_Ele27\_WP80 for electrons, using a tag-and-probe
585   approach. The tag is required to pass the full offline analysis selection and have \pt\ $>$ 30 GeV, $|\eta|<2.1$, and be matched to the single
586   lepton trigger. The probe is also required to pass the full offline analysis selection and have $|\eta|<2.1$, but the \pt\ requirement is relaxed to 20 GeV
587 < in order to measure the \pt\ turn-on curve. The tag-probe pair is required to have opposite-sign and an invariant mass in the range 76--106 GeV.
