"Seeing a single top quark: Search for pp->tqy production and The combination of ATLAS searches for flavor changing neutral currents in t->Hq decays"

Abstract: The top quark is the heaviest known elementary particle. With a coupling to the Higgs boson close to unity, the top quark plays a special role in electroweak symmetry breaking as well as in physics beyond the Standard Model. Accurate measurement of its properties can provide key information for understanding the physics at the TeV scale. In this talk, I will report two measurements of the top quark properties performed with Run-2 data collected by the ATLAS experiment at the LHC. First, I will outline the first-ever ATLAS search for the associated production of a single top quark and a photon. Next, I will present results from the combination of ATLAS searches for flavor changing neutral currents (FCNC) in t-> Hq decays.
