In this section, we interpret the results of the targeted search in the context of the \wzmet\ model depicted in Fig.~\ref{fig:diagrams} (right) |
| 5 |
|
and a gauge-mediated SUSY breaking (GMSB) model that produces a signature of \zzmet\ will be added. The results of the targeted search presented here |
| 6 |
|
will be combined with those of the trilepton ewkino search for the final \wzmet\ interpretation, and with the quadlepton ewkino search |
| 7 |
|
for the final GMSB \zzmet\ interpretation. |

The exclusion is performed using the results of simultaneous counting experiments in the five exclusive \MET\ signal regions defined by \MET\ $>$ 80 GeV, |

as summarized in Table~\ref{tab:results_targ} (commonly referred to as a ``shape analysis''). |

The upper limit calculation is performed with the LandS software using the LHC-type CLs criterion. |

The signal efficiency uncertainties include the luminosity (4.4\%), acceptance for the b-jet veto (4\%), lepton ID and isolation efficiency (2\% per lepton), |
| 13 |
+ |
and trigger efficiency (3\%). The uncertainty from JES is determined following the POG-recommended procedure, by varying the jet energies by the |
| 14 |
+ |
\pt- and $\eta$-dependent uncertainties and propagating this to the jet multiplicity, dijet mass, and \MET. |
| 15 |
+ |
The background uncertainties are quoted in Table~\ref{tab:results_targ}. For each background contribution, the uncertainty is assumed to be 100\% |
| 16 |
+ |
correlated across all signal regions. |

For the \wzmet\ model, the signal efficiency times acceptance and cross section upper limits are displayed in Fig.~\ref{fig:results_wzmet}, |
| 19 |
|
along with the observed and expected exclusion contours, which are compared to the 2011 observed exclusion contour. |

Figure~\ref{fig:results_wzmetpoints} shows the excluded points used to derive the exclusion contours. We note that the map of exclusion |
