Improving background estimation in events with multiple jets and at least one charged lepton

The ATLAS experiment searches for SUSY signal events with many jets and at least one charged lepton. The backgrounds for these signals are not well described by Monte Carlo generators. For the dominant $t\bar{t}$ background, the performance of several generators is compared. For the $W+$jets backgro...

description The ATLAS experiment searches for SUSY signal events with many jets and at least one charged lepton. The backgrounds for these signals are not well described by Monte Carlo generators. For the dominant $t\bar{t}$ background, the performance of several generators is compared. For the $W+$jets background, the charge asymmetry method as a tool for background estimation is investigated. Chances to improve the estimations of both backgrounds are indicated.
