Generalized messenger sector for gauge mediation of supersymmetry breaking and the soft spectrum

Understand

We consider a generic renormalizable and gauge invariant messenger sector and derive the sparticle mass spectrum using the formalism introduced for General Gauge Mediation.

• Our results recover many expressions found in the literature in various limits.
• Constraining the messenger sector with a global symmetry under which the spurion field is charged, we analyze Extraordinary Gauge Mediation beyond the small SUSY breaking limit.
• Finally, we include D-term contributions and compute their corrections to the soft masses.
