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,
|
| 10 |
as summarized in Table~\ref{tab:results_targ} (commonly referred to as a ``shape analysis'').
|
| 11 |
The upper limit calculation is performed with the LandS software using the LHC-type CLs criterion.
|
| 12 |
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.
|
| 17 |
|
| 18 |
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.
|
| 20 |
Figure~\ref{fig:results_wzmetpoints} shows the excluded points used to derive the exclusion contours. We note that the map of exclusion
|
| 21 |
contours appears quite ragged since for many of the points the cross section upper limit is very close to the theory cross section.
|
| 22 |
Therefore we do not expect the ragged exclusion region to be an issue for the final results since
|
| 23 |
we currently have 9.2 fb$^{-1}$ and expect the luminosity to increase significantly. A {\bf VERY APPROXIMATE} projection of the expected excluded region
|
| 24 |
for an integrated luminosity of 15 fb$^{-1}$ (a rough guess at the final HCP data sample) is obtained by scaling the expected cross section limits by
|
| 25 |
$\sqrt{(9.2 \rm{fb}^{-1})/(15 \rm{fb}^{-1})}$, as displayed in Fig.~\ref{fig:results_15fb}.
