Charginos and Neutralinos Beyond MSSMMariana Frank Abstract: After the discovery of the Higgs Boson, the LHC is poised to reopen, operating at centre of mass energy of 13 TeV, and to look for signals of physics beyond the Standard Model. Supersymmetry remains the favourite scenario, and if valid, it is likely to manifest itself in observations of signals coming from the production and decays of charginos and neutralinos. I analyse these in two models beyond the minimal scenario, one with extra higgsinos (fermionic partners of Higgs bosons), and one with extra gauginos (fermionic partners of gauge bosons), and show that the production is likely to be enhanced, and the decay modes altered. Investigating the final signal (into one, two, and three or more leptons) is likely to yield distinguishing signals for the models and offer indications of the extended gauge structure. |
