Review of BSM neutral Higgs results in ATLAS

The search for beyond Standard Model physics is an active area of study at the LHC. This article reviews beyond Standard Model neutral Higgs searches using Run 1 LHC proton-proton collision data with the ATLAS detector. Searches for neutral Higgs bosons decaying to $\tau\tau$ pairs, scalar particles decaying to $\gamma\gamma$ pairs, flavor-changing neutral currents involving Higgs bosons, di-Higgs decays to $b\bar{b}\gamma\gamma$ and $b\bar{b}b\bar{b}$, Higgs boson cascades and Higgs decaying to invisible particles are discussed. No significant deviations from Standard Model prediction are found, leading to tighter constraints on beyond Standard Model theories.
