Searches for BSM Higgs bosons in fermionic decays in ATLAS

Beyond the standard model theories such as the MSSM and other two-Higgs-doublet-models predict an extended Higgs sector. In some scenarios the additional Higgs bosons can have significant branching ratios to fermions. The ATLAS detector at the LHC has set stringent limits on beyond the standard model Higgs bosons from 36.1 fb$^{ -1}$ of proton-proton collision data collected in Run 2. This report summarises some of the searches for heavy neutral beyond the standard model Higgs bosons in τ and top final states.
