Search for charged Higgs bosons through the violation of lepton universality in tt? events using pp collision data at s = 7 TeV with the ATLAS experiment

Popis výsledku v původním jazyce

In several extensions of the Standard Model, the top quark can decay into a bottom quark and a light charged Higgs boson H (+), t??bH (+), in addition to the Standard Model decay t??bW. Since W bosons decay to the three lepton generations equally, whileH (+) maypredominantlydecayinto ??, charged Higgs bosons can be searched for using the violation of lepton universality in top quark decays. The analysis in this paper is based on 4.6 fb(1) of proton-proton collision data at TeV collected by the ATLAS experiment at the Large Hadron Collider. Signatures containing leptons (e or ?) and/or a hadronically decaying ? (? (had)) are used. Event yield ratios between e + ? (had) and e + ?, as well as between ? + ? (had) and? + e, final states are measured in thedata and compared to predictions from simulations. This ratio-based method reduces the impact of systematic uncertainties in the analysis.
