Searches for Beyond the Standard Model Higgs Bosons at ATLAS

Searches for beyond the Standard Model Higgs bosons with the ATLAS detector at the Large Hadron Collider are presented. The individual results are based on data-sets with integrated luminosities between $35,mathrm{pb}^{-1}$ and $1.6,mathrm{fb}^{-1}$ of proton-proton collisions at a centre-of-mass energy of $7,mathrm{TeV}$. No significant deviation from Standard Model predictions without a Higgs boson are observed. Exclusion limits are set on production cross sections as a function of the Higgs boson mass and in the parameter space of supersymmetric models.
