The searches for evidence of beyond the Standard Model (BSM) Higgs bosons is a crucial part of the LHC physics program. These searches are mainly driven by two approaches: directly from decays of neutral and charged Higgs bosons, indirectly by interpreting measured mass and couplings of light Higgs boson in extensions of the SM. This note reviews the most recent BSM Higgs boson searches performed with ATLAS at the LHC using Run 1 and early Run 2 proton-proton collision data. In particular, limits on new phenomena via coupling measurements, searches for charged and neutral Higgs bosons, double Higgs boson production and scalar particles decaying to gamma gamma are presented.

Abstract

The searches for evidence of beyond the Standard Model (BSM) Higgs bosons is a crucial part of the LHC physics program. These searches are mainly driven by two approaches: directly from decays of neutral and charged Higgs bosons, indirectly by interpreting measured mass and couplings of light Higgs boson in extensions of the SM. This note reviews the most recent BSM Higgs boson searches performed with ATLAS at the LHC using Run 1 and early Run 2 proton-proton collision data. In particular, limits on new phenomena via coupling measurements, searches for charged and neutral Higgs bosons, double Higgs boson production and scalar particles decaying to gamma gamma are presented. No significant deviations from the SM background expectations are found in any of the searches and thus the resulting exclusion limits are given.
