We count the number of events in region |

$A'$, defined in Sec.~\ref{sec:othBG} by replacing the above $\met/\sqrt{\rm SumJetPt}$ |
74 |
|
cut with the same cut on the quantity $P_T(\ell\ell)/\sqrt{\rm SumJetPt}$, |
75 |
< |
and find $N_{A'}=6$. To predict the yield in region A we take |
76 |

$N_A = K \cdot K_C \cdot N_{A'} = 10.4 \pm 4.2$ |
75 |

and find $N_{A'}=6$. We subtract off the expected DY contribution in this region |

$N_{DY} = 2.5 \pm 2.4$, derived in Sec.~\ref{sec:othBG}. |

To predict the yield in region A we take |

$N_A = K \cdot K_C \cdot ( N_{A'} - N_{DY} ) = 6.1 \pm 6.0$ |
79 |

(statistical uncertainty only, assuming Gaussian errors), |
80 |

Encouraged by the good agreement between predicted and observed yields |
85 |
|
in the control region, we proceed to perform the $P_T(\ell \ell)$ method |
88 |
|
Section~\ref{sec:othBG} to be the same as region $D$ but with the |
89 |
|
$\met/\sqrt{\rm SumJetPt}$ requirement |
90 |
|
replaced by a $P_T(\ell\ell)/\sqrt{\rm SumJetPt}$ requirement, |
91 |
< |

90 |
< |
$N_D = K \cdot K_C \cdot N_{D'} = 3.07 \pm 2.17$ where $K=1.54 \pm xx$ |
91 |

as derived in Sec.~\ref{sec:victory} and $K_C = 1$. |

is $N_{D'}=2$. |

We next subtract off the expected DY contribution of |
93 |
< |
{\color{red} \bf 0.8 $\pm$ 0.8 (update DY estimate)} events, as calculated |
94 |
< |
in Sec.~\ref{sec:othBG}. This gives a predicted yield of |

$N_D=1.8^{+2.5}_{-1.8}$ events, which is consistent with the observed yield of |
93 |

$N_{DY}$ = $0.4 \pm 0.4$ events, as calculated |
94 |

in Sec.~\ref{sec:othBG}. The BG prediction is |

$N_D = K \cdot K_C \cdot (N_{D'}-N_{DY}) = 2.5 \pm 2.2$ (statistical |

uncertainty only, assuming Gaussian errors), where $K=1.54 \pm xx$ |
97 |

as derived in Sec.~\ref{sec:victory} and $K_C = 1$. |

This prediction is consistent with the observed yield of |
