Model independent search for new phenomena in pp(bar) collisions at sqrt(s) =1.96 TeV

Abstract

We describe a model independent search for physics beyond the standard model in lepton final states. We examine 117 final states using 1.1 fb${}^{-1}$ of $p\bar{p}$ collisions data at $\sqrt{s}=1.96$ TeV collected with the D0 detector. We conclude that all observed discrepancies between data and model can be attributed to uncertainties in the standard model background modeling, and hence we do not see any evidence for physics beyond the standard model.
