denoted as follows: |

\begin{itemize} |

the range that maximises the significance as shown in |
| 116 |
|
Figure~\ref{fig:s_vs_wlpt}. |

An additional requirement on the isolation between electron and muons is applied |
| 119 |
+ |
for the $2\mu 1e$ channel, by demanding $\Delta R$ between the electron associated |
| 120 |
+ |
to the \W-decay and any of the two muons associated to the \Z-decay be greater than |
| 121 |
+ |
0.1. This requirement allows to suppress the contributions of $\Z \to \mu\mu$ |
| 122 |
+ |
decays, where one of the two muons radiates a photon which is reconstructed |
| 123 |
+ |
as electrons, possibly after conversion, which shows up as a peak at around 60 GeV |
| 124 |
+ |
in the Z mass distribution, as shown in figure~\ref{fig:Z2mu1e_60GeVPeak}. |

The expected number of events passing the various steps of the selection |

is listed in Tables~\ref{tab:sel-effA} and~\ref{tab:sel-effB}. |
