Tools for estimating fake/non-prompt lepton backgrounds with the ATLAS detector at the LHC

G. Aad,
B. Abbott,
D.C. Abbott
et al.

Abstract: Measurements and searches performed with the ATLAS detector at the CERN LHC often involve signatures with one or more prompt leptons. Such analyses are subject to `fake/non-prompt' lepton backgrounds, where either a hadron or a lepton from a hadron decay or an electron from a photon conversion satisfies the prompt-lepton selection criteria. These backgrounds often arise within a hadronic jet because of particle decays in the showering process, particle misidentification or particle interactions with the detect… Show more
