In this note a deep review of the current official criteria for
|
| 2 |
|
|
ElectronID have been performed. This study has been done using $WZ
|
| 3 |
|
|
\rightarrow e^\pm \nu \mu^+ \mu^-$ where the $Z$ decaying into muons
|
| 4 |
|
|
will serve to select the event. The main background for such analysis
|
| 5 |
|
|
is $Z+jets$ production. Using the official robust cuts for this
|
| 6 |
|
|
analysis, we end up with a significance for 1fb$^{-1}$ of the order of
|
| 7 |
|
|
0.9. Taking such criteria as a starting point, new threshold have been
|
| 8 |
|
|
designed first to improve the significance of such channel then new
|
| 9 |
|
|
variable have been studied in order to select isolated electrons. With
|
| 10 |
|
|
this simple criteria which are using 6 variables with 2 set of
|
| 11 |
|
|
threshold (one for barrel, the second for endcap), we end up on the
|
| 12 |
|
|
same channel with a significance of 3.7 for 1fb$^{-1}$ integrated
|
| 13 |
|
|
luminosity.
