Beyond Standard Model Higgs Searches at the LHC

This is a talk for the conference Weak Interactions and Neutrinos '09. An overview of searches for non Standard Model Higgs Boson searches of ATLAS and CMS is given. In particular, neutral and charged Higgs boson searches in the MSSM are presented. Because of the relatively high branching ratios and the possibility to trigger on and identify tau leptons, decays into a tau lepton pair play an important role in discovery. Muon pairs from Higgs are much rarer but have the advantage of a very clear signal. Alternative approaches via neutralino decays and reinterpretation of Standard Model searches are discussed. Analyses to find charged MSSM Higgs bosons are presented. Two examples of non-supersymmetric searches, invisible Higgs and search for radions are also given.
