1 claudioc 1.1 \section{Trigger efficiency}
2     \label{sec:trgEff}
3    
4 claudioc 1.2 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.
15 benhoob 1.4 Details are given in App.~\ref{sec:appendix_trigger}.
16 claudioc 1.3
17     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.
21    
22     \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.
24     We need to wait for the xx in the previous section to be completes before we can
25     fill out this table.}
