Beschreibung:
  • A search for single top quark production is performed in the full e ± p data sample collected by the H1 experiment at HERA, corresponding to an integrated luminosity of 474 pb -1. Decays of top quarks into a b quark and a W boson with subsequent leptonic or hadronic decay of the W are investigated. A multivariate analysis is performed to discriminate top quark production from Standard Model background processes. An upper limit on the top quark production cross section via flavour changing neutral current processes σ (e p → e t X) < 0.25 pb is established at 95% CL. Limits on the anomalous coupling κ t u γ are derived. © 2009 Elsevier B.V.
