Description
The top quark can be used as a probe of new physics, particularly when it decays into non-SM particles. One promising example is the decay of a top quark into a charged Higgs boson and b-quark. Charged Higgs bosons occur naturally in extended Higgs sectors and for a wide range of models can decay nearly exclusively into a tau lepton and a neutrino. In this talk, we summarize the searches for tau leptons from SM top quark pair production and decay, and their interpretation as a probe of physics beyond the standard model using the ATLAS detector.
