In Figure~\ref{fig:AllFits}, the fit approximation of the invariant
|
| 7 |
beaucero |
1.1 |
mass of \Z boson candidate is shown for each channel and for loose and
|
| 8 |
|
|
tight criteria. The fit is performed using an addition of a
|
| 9 |
|
|
convolution of a Gaussian and Breit-Wigner function and a line in
|
| 10 |
beaucero |
1.4 |
order to fit the background. It has to be noticed that due to a lack
|
| 11 |
vuko |
1.8 |
of statistics in chowder soup, all bins with 0 events from chowder have
|
| 12 |
beaucero |
1.4 |
been modified in order to avoid to have an error at 0. The
|
| 13 |
|
|
corresponding error in the bin with no event correspond to the weight
|
| 14 |
|
|
of each process in Chowder soup. One can see that the errors are
|
| 15 |
vuko |
1.8 |
large, and the fit is then not really constrained.

The linear fit will take into account the background with non-genuine
|
| 31 |
|
|
\Z candidate but it will also account for some part of \Z+jets and
|
| 32 |
|
|
$Zb\bar{b}$ background as the gamma$^*$ will populate the side band.
