The above procedure is applied to MC to test its effectiveness under `ideal' conditions.
|
| 6 |
|
|
In order to test the
|
| 7 |
|
|
results obtained in section \ref{sec:tempcompresults},
|
| 8 |
|
|
%dependence of the method on the sample composition,
|
| 9 |
|
|
we construct templates separately from PhotonJet MC and QCD MC.
|
| 10 |
|
|
%Templates are derived from PhotonJet MC, and
|
| 11 |
|
|
These templates are then used to predict the MET distribution in ZJets MC. The
|
| 12 |
|
|
MC samples used are:

Good agreement between the observed and predicted MET distributions is observed for each MC sample,
|
| 45 |
|
|
as well as between the two samples, as shown in figures \ref{fig:mcclosurepho} and \ref{fig:mcclosureqcd}.
|
| 46 |
|
|
Note that the low equivalent luminosity of the QCD samples ($\approx$ 300/pb) explains the lack of
|
| 47 |
|
|
statistics in the tails.
