Searches for BSM Higgs Bosons at the LHC

An overview of the searches for Higgs bosons in different extensions of the Standard Model of particle physics are presented. These extensions predict additional neutral and charged Higgs Bosons; The Minimal Supersymmetric extension of the Standard Model (MSSM), the next-to Minimal Supersymmetric extension of the Standard Model (nMSSM), two Higgs doublet models, four-generation and fermiophobic and other models are considered. The results are based on the data collected in 2011 and 2012 by the LHC experiments ATLAS and CMS in proton-proton collisions at a center-of-mass energy of 7 TeV and 8 TeV respectively. No excess was found neither in the charged nor in the neutral Higgs Boson searches. Both model-independent and model-dependent exclusion limits were therefore set. The exclusion limits in the context of the MSSM are presented both on the branching ratio and for the $m^{max}_{h}$ scenario in the $m_{A}$ vs. $tan\beta$ and in the $m_{H^{+}}$ vs. $tan\beta$ plane, respectively.
