Searches for neutral 2HDM, MSSM and NMSSM Higgs bosons at the LHC

After a Higgs boson with a mass of 125 GeV has been discovered, it is still unclear whether this is the Higgs boson of the Standard Model or whether it is part of an extended Higgs sector, which is predicted by various models of new physics such as the minimal supersymmetric extension to the Standard Model. Recent results of direct searches for additional, neutral Higgs bosons by the ATLAS and CMS experiments are reviewed, which are based on pp collision data collected at centre-of-mass energies of 7 and 8 TeV corresponding to integrated luminosities of approximately 5 and 20$\,\mathrm{fb}^{-1}$, respectively.
