This CR consists of events that pass all cuts but fail the isolated |
| 5 |
|
track veto cut. These events (especially in the tail of $M_T$) are |
| 6 |
|
predominantly $t\bar{t}$ dileptons. Thus the test in this control |
| 7 |
< |
regions is similar to that performed in CR4 and described |

in Section~\ref{sec:CR4-valid}. There is some non-trivial |

taus and events with electrons or muons below the threshold of |

Next we define a ``post-veto'' sample as the events that have an |
| 32 |
< |
isolated track. The $t\bar{t} \to \ell +$ jets component is |
| 33 |

normalized in this sample, again by normalizing ti the $M_T$ peak |

(note that we use the term ``post-veto'' to refer to the application of the isolated track cut of the sample, which in this case is an isolated track requirement). |
