These backgrounds are small, contributing at the $\sim 5\%$ level and their predictions are taken |
10 |
|
from MC, normalized to the corresponding cross sections. A $50\%$ systematic uncertainty is |
11 |
|
assigned for all these backgrounds. |

Note that these backgrounds are not double-counted because the contribution to the \mt\ peak region |
13 |
+ |
is subtracted off when deriving the \mt\ peak data/MC scale factors. %HOOBERMAN: correct? |

Backgrounds from QCD are expected to be small in the signal regions with large \mt\ and \met. |
