Encouraged by the good agreement between predicted and observed yields |
| 83 |
|
in the control region, we proceed to perform the $P_T(\ell \ell)$ method |
| 86 |
|
Section~\ref{sec:othBG} to be the same as region $D$ but with the |
| 87 |
|
$\met/\sqrt{\rm SumJetPt}$ requirement |
| 88 |
|
replaced by a $P_T(\ell\ell)/\sqrt{\rm SumJetPt}$ requirement, |
| 89 |

is $N_{D'}=2$. Thus the BG prediction is |

$N_D = K \cdot K_C \cdot N_{D'} = 3.07 \pm 2.17$ where $K=1.54 \pm xx$ |

We next subtract off the expected DY contribution of |

{\color{red} \bf 0.8 $\pm$ 0.8 (update DY estimate)} events, as calculated |
