events in the signal region (region $D$). The Standard Model |

The data yields in the |
| 24 |
|
four regions are summarized in Table~\ref{tab:datayield}. |

The prediction of the ABCD method is is given by $AC/B$ and |
| 26 |

is 0.5 events. |

The prediction of the ABCD method is is given by $A\times C/B$ and |
