Is gauge mediation in the swampland?

We note that the typical gauge mediation of supersymmetry breaking is in tension with the global limit of the festina lente swampland bound. The alternatives are mediation/breaking schemes that decouple together with gravity, as for example gravity mediation, for which we highlight some basic phenomenological properties. Gauge mediation remains instead a viable mechanism only in models where supersymmetry is restored in the global limit, as for example in no-scale supergravity. & COPY; 2023 The Author(s).

Automated summary

We observe the conflict between the typical gauge mediation of supersymmetry breaking and the global limit of the festina lente swampland bound. The viable alternatives include decoupling mediation/breaking schemes along with gravity, such as gravity mediation, with some highlighted phenomenological properties. On the other hand, gauge mediation remains a possible mechanism only in models where supersymmetry is restored in the global limit, such as in no-scale supergravity.
