Sweet Spot Supersymmetry and Composite Messengers

Understand

Sweet spot supersymmetry is a phenomenologically and cosmologically perfect framework to realize a supersymmetric world at short distance.

• We discuss a class of dynamical models of supersymmetry breaking and its mediation whose low-energy effective description falls into this framework.
• Hadron fields in the dynamical models play a role of the messengers of the supersymmetry breaking.
• As is always true in the models of the sweet spot supersymmetry, the messenger scale is predicted to be 10^5 GeV < M_mess < 10^{10} GeV.
