\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}. Currently we blind the observed data yields for the signal regions, defined by \MET\ $>$ 100 GeV. |
| 8 |
< |
These yields will be presented when the decision is made to unblind the Z region for the Aachen/ETH low-mass opposite-sign same-flavor |
| 9 |
< |
dilepton analysis (``edge analysis''). In the low \MET\ region, we observe good agreement between the data and the predicted background, |
| 10 |
< |
which validates the background estimation methodology. |
