%0 Journal Article %T Data-driven Estimations of Z, W and Top Backgrounds %A Mark Hodgkinson %A for the ATLAS Collaboration %J Physics %D 2008 %I arXiv %X The Standard Model processes of W, Z and top quark production in association with jets constitute a major background to searches for Supersymmetry at the LHC. We describe recent work performed in the ATLAS Collaboration to estimate these backgrounds for a basic SUSY selection, and we discuss methods to derive them from the first ATLAS data. %U http://arxiv.org/abs/0809.4915v2
