description | I summarize a recent study by the GAMBIT Collaboration in which we investigated the combined collider constraints on the chargino and neutralino sector of the Minimal Supersym-metric Standard Model. Through a large fit using GAMBIT we found that current ATLAS and CMS results with 36 fb$^{-1}$ of 13 TeV LHC collision data do not provide a general constraint on the lightest neutralino and chargino masses. Further, we found that a pattern of excesses in some of the LHC analyses can be fit in a subset of the model parameter space. The excess has an estimated local significance of 3.3σ based on the 13 TeV results alone, and 2.9σ when 13TeV and 8 TeV results are combined. |
