Searches for additional neutral Higgs bosons in ATLAS

The discovery of the Higgs boson with a mass of about 125 GeV completed the observation of the particle content predicted by the Standard Model. Even though this model is well established and consistent with many measurements, it is not considered complete as it is not capable of explaining some experimental observations. Many extensions of the Standard Model addressing such shortcomings introduce additional Higgs-like bosons. A selection of searches for additional high- and low-mass neutral Higgs bosons based on the full LHC Run 2 dataset of the ATLAS experiment at 13 TeV is presented in this contribution.
