In the limit setting we also include the uncertainties from trigger efficiency, |

We set upper limits on the non-SM contributions to the high \MET\ and high \Ht\ signal regions. |

For both regions, we find reasonable agreement between the observed yields and the predictions from MC and from the 2 |
| 14 |
|
data-driven methods. We choose here to extract the upper limits using the MC prediction for the |
| 15 |
|
background estimate. The 95\% CL upper limit is extracted using a Bayesian technique~\cite{ref:cl95cms}, |

with a log-normal model of nuissance parameter integration assuming 0 signal . The results are summarized in |

Table~\ref{tab:results}. Based on these results, we exclude LM1 and LM3. |
