摘要：The top quark and its properties within and beyond the Standard Model will be extensively studied
at the incoming Large Hadron Collider. Nonetheless the top quark will play the role of the main
background for most of the Higgs and new physics searches. In this paper the top as a background
to H !W+W !l+n ln¯ Higgs channel will be studied. The current status of the Monte Carlo
tools for tt and single top simulation will be presented. Finally the problem on how to evaluate
the top background from the data will be addressed and the related systematics will be discussed.
