\section{Results} |

< |
In this section we provide the results of the inclusive and targeted searches. The observed and predicted \MET\ distributions for the |
| 6 |
< |
inclusive analysis are indicated in Fig.~\ref{fig:results_incl}. A summary of the results in the signal regions is provided in |
| 7 |
< |
Table~\ref{tab:results_incl}. In the low \MET\ region (\MET\ $<$ 100 GeV) which is dominated by the \zjets\ background, the observed |
| 8 |
< |
yields are in good agreement with the predicted background. This is also the case in the high \MET\ tail (\MET\ $>$ 200 GeV). |
| 9 |
< |
In the moderate \MET\ region (100 $<$ \MET $<$ 200 GeV) we observe a slight excess in the data with respect to the predicted background. |
| 10 |
< |
Taking into account the full uncertainty on the background prediction, the significance of the excess is about 1.3$\sigma$. |
| 11 |
< |
The separate results for the ee and $\mu\mu$ channels are presented in App.~\ref{app:results}. For this \MET\ region, we find an excess |
| 12 |
< |
of 1.4$\sigma$ in the ee channel and 0.7$\sigma$ in the $\mu\mu$ channel. |
