Beyond Standard Model searches with top quarks at ATLAS

摘要

At the LHC, the top quark is expected to provide a huge and cleansignal. With about eight millions of expected top pairs arid three millions of singletop events produced per year in the low luminosity runs, and with a low level ofbackgrounds, the LHC will open a new opportunity for precision measurements ofthe top quark properties and for exotic topology searches involving top quarks. Asthe ATLAS discovery potential on new physics with top quarks is being assessedwith many analyses, this paper focuses on two particular topics: heavy neutralresonances and charged Higgs boson searches with top quarks. The analyses andthe ATLAS expectations are described.
