The MC yields are normalized to 30 pb$^{-1}$ using the cross-sections |

As anticipated, the MC predicts |

|
that the preselection is dominated by $t\bar{t}$. The data yield is |

< |
in good agreement with the prediction. |

in good agreement with the prediction. Also shown are the yields for LM0 |

and LM1, two of the LM points which are benchmarks for SUSY analyses at CMS. |
