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.
