Collider constraints on electroweakinos in the presence of a light gravitino
The GAMBIT Collaboration, Viktor Ananyev, Csaba Balázs +19
Using the GAMBIT global fitting framework, we constrain the MSSM with an eV-scale gravitino as the lightest supersymmetric particle, and the six electroweakinos (neutralinos and ch…

Freeze-in production of decaying dark matter in five steps
Saniya Heeba, Felix Kahlhoefer, Patrick Stöcker
We study the cosmological evolution and phenomenological properties of scalar bosons in the keV to MeV range that have a tiny mixing with the Standard Model Higgs boson. The mixing…
