Abstract
Sweet spot supersymmetry is a phenomenological effective Lagrangian of weak scale supersymmetry with a certain set of natural assumptions. This framework is designed to avoid problems in low-energy phenomenology and cosmology of supersymmetric models. 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 105 GeV≲Mmess≲1010 GeV. Various values of the effective number of messenger fields Nmess are possible depending on the choice of the gauge group.
