In Tables~\ref{tab:wz-matcheffi-Zee} and \ref{tab:wz-matcheffi-Zmumu} we
|
| 7 |
|
|
display the fraction of reconstructed \WZ events with correctly-matched leptons.
|
| 8 |
|
|
It can be seen that the lepton associated with the \W boson decay is correctly matched
|
| 9 |
ymaravin |
1.4 |
to the true Monte Carlo lepton in more than 91\% of the cases for $3e$, 93\% for $3\mu$, and more
|
| 10 |
|
|
than 99\% for other categories , even for events with several lepton candidates available to be associated
|
| 11 |
vuko |
1.1 |
to the \W boson decay. The choice to take the lepton candidate with the leading $p_T$ is,
|
| 12 |
|
|
therefore, justified.
