in the $D'$ region. |

We find $N^{D'}(ee+\mu\mu)=2$, $N^{D'}(e\mu)=0$, |

$R^{D'}_{out/in}=0.4\pm0.3$ (stat.). |

$R^{D'}_{out/in}=0.18\pm0.16$ (stat.). |

Thus we estimate the number of Drell Yan events in region $D'$ to |

be $0.8\pm X$. |

We also perform the DY estimate in the region $A'$. Here we find |

$N^{A'}(ee+\mu\mu)=5$, $N^{A'}(e\mu)=0$, |

$R^{D'}_{out/in}=0.50\pm0.43$ (stat.), giving an estimated |

This Drell Yan method could also be used to estimate |
| 96 |
|
the number of DY events in the signal region (region $D$). |
