As described in Section~\ref{sec:trigSel} we rely on a
|
5 |
|
|
mixture of single and double lepton triggers. The trigger
|
6 |
|
|
efficiency is very high because for most of the phase space
|
7 |
|
|
we have two leptons each of which can fire a single lepton
|
8 |
|
|
trigger -- and the single lepton triggers are very efficient.
|
9 |
|
|
|
10 |
|
|
We apply to MC events a simplified model of the trigger efficiency
|
11 |
|
|
as a function of dilepton species ($ee$, $e\mu$, $\mu\mu$), the $P_T$
|
12 |
|
|
of the individual leptons, and, in the case of muons, the $|\eta|$
|
13 |
|
|
of the muons. We believe that this model is adequate for
|
14 |
|
|
the trigger efficiency precision needed for this analysis.

We take the trigger efficiency for $ee$ as 100\%. The trigger efficiency
|
18 |
|
|
for the $e\mu$ and $\mu\mu$ final states is summarized in Figures xx.
|
19 |
|
|
We estimate the systematic uncertainties on the trigger modeling
|
20 |
|
|
to be at the few percent level.

\noindent {\color{red}Figure xx will be a two dimensional table of the
|
23 |
|
|
trigger efficiency as a function of the pt of the two leptons.

|

We need to wait for the xx in the previous section to be completes before we can

fill out this table.}
