This is a search for new physics contributions to |

events with high \met and lots of jet activity. |

As seen in Section~\ref{sec:results}, there is no |

|
Nevertheless, we can make general statements about the |

systematic uncertainties, including quantitative |

estimates of the systematic uncertainties associated with |

The systematic uncertainty on the lepton acceptance consists |

of two parts: the trigger efficiency uncertainty and the |
