Description
To recognise supersymmetric decays or other rare processes, the standard model background for these signatures have to be predicted as precisely as possible. At the CMS experiment the reference analysis 2 is looking for supersymmetry in the purely hadronic channel. In this talk a data driven background estimate to this analysis for the ttbar and W+jet channel with muons or electrons in the final state on the basis of a cut inversion of the lepton veto cut is presented.
