The systematic uncertainty on the lepton acceptance consists |
| 18 |
|
of two parts: the trigger efficiency uncertainty and the |

ID and isolation of uncertainty. We discuss these in turn. |

The trigger efficiency |
| 22 |
|
for two leptons of $P_T>10$ GeV, with one lepton of |
| 65 |
|
the final state. For example, in MC we find that the |
| 66 |
|
lepton isolation efficiency differs by $\approx 4\%$ |
| 67 |
|
{\bf per lepton} between $Z$ events and $t\bar{t}$ events\cite{ref:top}. |

associated with the jet and $\met$ energy scale. The impact |
