ATLAS searches for heavy Higgs bosons and supersymmetry using tau decays

Results from the ATLAS experiment from searches for heavy Higgs bosons and supersymmetry with tau leptons in the final states are presented. The analyses discussed use datasets corresponding to approximately 13-15 fb−1 of 13 TeV proton-proton collision data taken in the years 2015-2016. No significant excess above the Standard Model is observed, and limits are set on new physics in various supersymmetric scenarios.
