Search for Higgs Bosons Beyond the Standard Model with the CMS Experiment at the LHC
Roger Wolf (Karlsruher Institut für Technologie)
DESY Auditorium, 16.45 h
After an inclusive analysis of its coupling structure the particle that has been discovered at the LHC is compatible with the predictions of a standard model (SM) Higgs boson with a mass of 125 GeV, within an accuracy of 10%. However, these measurements still have a large uncertainty, which leaves room for a branching fraction of roughly 30% into potentially new, yet, undiscovered final states. Also the discovered Higgs boson could well be interpreted as the first particle of a model describing physics beyond the SM (BSM). The observation of a second Higgs boson remains a smoking gun signature for any BSM model. In this seminar an overview will be given of parts of the rich program of BSM Higgs boson searches that have been performed with the CMS experiment on the LHC run-1 data. Such an overview cannot be complete. The presented searches will mostly be guided by the expectations of supersymmetric extensions of the SM.
