Sweet Spot Supersymmetry and Composite Messengers

[摘要] 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{sup 5} GeV {approx}< M{sub mess} {approx}< 10{sup 10} GeV. Various values of the effective number of messenger fields N{sub mess} are possible depending on the choice of the gauge group.
