Searches for additional Higgs bosons at CMS

The discovery of a Higgs boson with a mass of about 125 GeV by the ATLAS and CMS experiments at the LHC in 2012 validated the standard model (SM) mechanism in which the particles acquire mass through the spontaneous breaking of the electroweak symmetry. The measurements of the Higgs boson properties are, so far, consistent with the expectations of the standard model. However, beyond the SM theories such as the Two Higgs Doublet Models (2HDM), can also predict a Higgs boson with properties compatible with the observed 125 GeV boson and generate a rich and exciting phenomenology, including the presence of additional Higgs bosons. The results of recent searches for these additional Higgs bosons based on the full LHC Run 2 dataset of the CMS experiment at 13 TeV are presented
