Additional contributions to the single lepton sample arise from \wjets\ and single top. The combination of |
| 15 |
|
all single lepton backgrounds, \ttlj, \wjets\ and single top, comprises $\sim 15\%$ of the signal sample. |

|
Finally, other background sources such as dibosons, \dy\ + jets, in addition to rarer processes such as \ttbar\ |

produced in association with a vector boson and tribosons, provide a combined contribution to the signal sample |

at the level of $\sim 5\%$. |

Finally, the QCD background contribution is small, particularly in the signal sample, with a large \met\ requirement. |
