英文摘要	Using the GAMBIT global fitting framework, we constrain theMSSMwith an eV-scale gravitino as the lightest supersymmetric particle, and the six electroweakinos (neutralinos and charginos) as the only other light new states. We combine 15 ATLAS and 12 CMS searches at 13TeV, along with a large collection of ATLAS and CMSmeasurements of StandardModel signatures. This model, which we refer to as the (G) over tilde -EWMSSM, exhibits quite varied collider phenomenology due to its many permitted electroweakino production processes and decay modes. Charcteristic (G) over tilde -EWMSSM signal events have two or more Standard Model bosons and missing energy due to the escaping gravitinos. While much of the (G) over tilde -EWMSSM parameter space is excluded, we find several viable parameter regions that predict phenomenologically rich scenarios with multiple neutralinos and charginos within the kinematic reach of the LHC during Run 3, or the High Luminosity LHC. In particular, we identify scenarios with Higgsino-dominated electroweakinos as light as 140GeV that are consistent with our combined set of collider searches and measurements. The full set of (G) over tilde -EWMSSM parameter samples and GAMBIT input files generated for this work is available via Zenodo.
