Search for Higgs bosons beyond the Standard Model in b-quark final states at the CMS experiment

While the existence of a Higgs boson with a mass near 125 GeV has been clearly established, the detailed structure of the entire Higgs sector is yet unclear. Besides the standard model interpretation, well-motivated models with extended Higgs sectors are being considered. Such options include the minimal and next-to-minimal supersymmetric extensions (MSSM and NMSSM) of the Standard Model. Direct searches for additional Higgs bosons in b-quark final states are a promising way to address this key question. This article presents recent results from the CMS experiment.
