We examine the contribution of possible signal events in the \ttll\ |

control regions (CR4 and CR5). It should be emphasized that these |

As a result, if signal events were to populate these control regions |

this would not lead to an increase in the predicted background. |

To illustrate how much signal is expected to populate these control |

However, based on the fact that the CR4 and CR5 are not used to extract |
