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 |

region is similar to that performed in CR4 and described |
| 8 |
|
in Section~\ref{sec:CR4-valid}. There is some non-trivial |
| 9 |
|
complementarity because CR5 also includes events with |
| 10 |
|
taus and events with electrons or muons below the threshold of |
| 23 |
|
We define a ``pre-veto'' sample as the sample of events that pass |
| 24 |
|
all cuts without any isolated track requirements. This sample is |
| 25 |
|
dominated by $t\bar{t} \to \ell +$ jets. We normalize the dilepton |
| 26 |
< |
component of the top MC to that sample (NEED TO EXPLAIN EXACTLY HOW). |

component of the top MC to that sample. This is done by normalizing |
| 27 |

the total \ttbar\ MC to the $M_T$ peak region, $50 < M_T < 80$ GeV |
| 28 |

in this sample. |

|

|
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 (ALSO, NEED TO EXPLAIN HOW, EXACTLY). |
| 32 |
> |
isolated track |
| 33 |
> |
(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). |
| 34 |
> |
The $t\bar{t} \to \ell +$ jets component is |
| 35 |
> |
normalized in this sample, again by normalizing to the $M_T$ peak |
| 36 |
> |
region. |
| 37 |
|
These normalization factors are summarized in Table~\ref{tab:cr5mtsf}. |
| 38 |
|
|
| 39 |

The post-veto $\ttdl$ is taken from MC, but with scale factor obtained |
| 40 |
+ |
by the normalization of the ``pre-veto'' sample. |
| 41 |

|
| 42 |
|
The underlying \met\ and $M_T$ distributions are shown in |
| 43 |
|
Figures~\ref{fig:cr5met} and~\ref{fig:cr5mtrest}. The data-MC agreement |
| 44 |
|
is quite good. Quantitatively, this is also shown in Table~\ref{tab:cr5yields}. |

This is the second key test of the \ttdl\ modeling |
