Description
I will present the latest work on electroweak supersymmetry from the GAMBIT collaboration. With GAMBIT we have performed a large-scale fit of the electroweakino (neutralino and chargino) sector of the MSSM. The fit incorporates simulations of several recent ATLAS and CMS SUSY searches, in addition to constraints from SUSY searches at LEP and the invisible decay widths of the Z and Higgs bosons. When considering the general four-dimensional electroweakino parameter space, we find that current results do not robustly exclude any range of electroweakino masses. Further, due to multiple small excesses in the data, there is a weak preference for a scenario where all electroweakinos are lighter than ~500 GeV. I will also present preliminary results from ongoing follow-up studies, looking at electroweakino models beyond the MSSM.
